These crates are modularly constructed to allow an easy replacement of parts like fan trays or power supplies. Combining superiorly designed ruggedized chassis with highly sophisticated low noise power supplies and a high level of integrated diagnostic and monitoring circuits W-IE-NE-R crates are state of the art of electronic packaging. Outstanding features include remote monitoring and control via CANbus, Ethernet, RS 232 / Telnet and USB which is enhanced by powerful software products like WinCRM and OPC server. In addition to the standard crate lines WIENER is specialized in providing customer specified crates. Taking advantage of the modular design of all crate components, modifications and special versions can be produced without significant increases in price and delivery time.

  • The Particle Zoo
    219 8 The Particle Zoo 8.1 Introduction Around 1960 the situation in particle physics was very confusing. Elementary particlesa such as the photon, electron, muon and neutrino were known, but in addition many more particles were being discovered and almost any experiment added more to the list. The main property that these new particles had in common was that they were strongly interacting, meaning that they would interact strongly with protons and neutrons. In this they were different from photons, electrons, muons and neutrinos. A muon may actually traverse a nucleus without disturbing it, and a neutrino, being electrically neutral, may go through huge amounts of matter without any interaction. In other words, in some vague way these new particles seemed to belong to the same group of by Dr. Horst Wahl on 08/28/12. For personal use only. particles as the proton and neutron. In those days proton and neutron were mysterious as well, they seemed to be complicated compound states. At some point a classification scheme for all these particles including proton and neutron was introduced, and once that was done the situation clarified considerably. In that Facts And Mysteries In Elementary Particle Physics Downloaded from www.worldscientific.com era theoretical particle physics was dominated by Gell-Mann, who contributed enormously to that process of systematization and clarification. The result of this massive amount of experimental and theoretical work was the introduction of quarks, and the understanding that all those ‘new’ particles as well as the proton aWe call a particle elementary if we do not know of a further substructure.

  • CERN Courier–Digital Edition
    CERNMarch/April 2021 cerncourier.com COURIERReporting on international high-energy physics WELCOME CERN Courier – digital edition Welcome to the digital edition of the March/April 2021 issue of CERN Courier. Hadron colliders have contributed to a golden era of discovery in high-energy physics, hosting experiments that have enabled physicists to unearth the cornerstones of the Standard Model. This success story began 50 years ago with CERN’s Intersecting Storage Rings (featured on the cover of this issue) and culminated in the Large Hadron Collider (p38) – which has spawned thousands of papers in its first 10 years of operations alone (p47). It also bodes well for a potential future circular collider at CERN operating at a centre-of-mass energy of at least 100 TeV, a feasibility study for which is now in full swing. Even hadron colliders have their limits, however. To explore possible new physics at the highest energy scales, physicists are mounting a series of experiments to search for very weakly interacting “slim” particles that arise from extensions in the Standard Model (p25). Also celebrating a golden anniversary this year is the Institute for Nuclear Research in Moscow (p33), while, elsewhere in this issue: quantum sensors HADRON COLLIDERS target gravitational waves (p10); X-rays go behind the scenes of supernova 50 years of discovery 1987A (p12); a high-performance computing collaboration forms to handle the big-physics data onslaught (p22); Steven Weinberg talks about his latest work (p51); and much more.

    Planck Mass Rotons as Cold Dark Matter and Quintessence* F. Winterberg Department of Physics, University of Nevada, Reno, USA Reprint requests to Prof. F. W.; Fax: (775) 784-1398 Z. Naturforsch. 57a, 202–204 (2002); received January 3, 2002 According to the Planck aether hypothesis, the vacuum of space is a superfluid made up of Planck mass particles, with the particles of the standard model explained as quasiparticle – excitations of this superfluid. Astrophysical data suggests that ≈70% of the vacuum energy, called quintessence, is a neg- ative pressure medium, with ≈26% cold dark matter and the remaining ≈4% baryonic matter and radi- ation. This division in parts is about the same as for rotons in superfluid helium, in terms of the Debye energy with a ≈70% energy gap and ≈25% kinetic energy. Having the structure of small vortices, the rotons act like a caviton fluid with a negative pressure. Replacing the Debye energy with the Planck en- ergy, it is conjectured that cold dark matter and quintessence are Planck mass rotons with an energy be- low the Planck energy.

  • Absence of Landau Damping in Driven Three-Component Bose–Einstein
    www.nature.com/scientificreports OPEN Absence of Landau damping in driven three-component Bose– Einstein condensate in optical Received: 19 June 2017 Accepted: 10 July 2018 lattices Published: xx xx xxxx Gavriil Shchedrin, Daniel Jaschke & Lincoln D. Carr We explore the quantum many-body physics of a three-component Bose-Einstein condensate in an optical lattice driven by laser felds in V and Λ confgurations. We obtain exact analytical expressions for the energy spectrum and amplitudes of elementary excitations, and discover symmetries among them. We demonstrate that the applied laser felds induce a gap in the otherwise gapless Bogoliubov spectrum. We fnd that Landau damping of the collective modes above the energy of the gap is carried by laser-induced roton modes and is considerably suppressed compared to the phonon-mediated damping endemic to undriven scalar condensates Multicomponent Bose-Einstein condensates (BECs) are a unique form of matter that allow one to explore coherent many-body phenomena in a macroscopic quantum system by manipulating its internal degrees of freedom1–3. Te ground state of alkali-based BECs, which includes 7Li, 23Na, and 87Rb, is characterized by the hyperfne spin F, that can be best probed in optical lattices, which liberate its 2F + 1 internal components and thus provides a direct access to its internal structure4–11. Driven three-component F = 1 BECs in V and Λ confgurations (see Fig. 1(b) and (c)) are totally distinct from two-component BECs3 due to the light interaction with three-level systems that results in the laser-induced coherence between excited states and ultimately leads to a number of fascinating physical phenomena, such as lasing without inversion (LWI)12,13, ultraslow light14,15, and quantum memory16.

  • Physical Vacuum Is a Special Superfluid Medium
    Physical vacuum is a special superfluid medium Valeriy I. Sbitnev∗ St. Petersburg B. P. Konstantinov Nuclear Physics Institute, NRC Kurchatov Institute, Gatchina, Leningrad district, 188350, Russia; Department of Electrical Engineering and Computer Sciences, University of California, Berkeley, Berkeley, CA 94720, USA (Dated: August 9, 2016) The Navier-Stokes equation contains two terms which have been subjected to slight modification: (a) the viscosity term depends of time (the viscosity in average on time is zero, but its variance is non-zero); (b) the pressure gradient contains an added term describing the quantum entropy gradient multiplied by the pressure. Owing to these modifications, the Navier-Stokes equation can be reduced to the Schr¨odingerequation describing behavior of a particle into the vacuum being as a superfluid medium. Vortex structures arising in this medium show infinitely long life owing to zeroth average viscosity. The non-zero variance describes exchange of the vortex energy with zero-point energy of the vacuum. Radius of the vortex trembles around some average value. This observation sheds the light to the Zitterbewegung phenomenon. The long-lived vortex has a non-zero core where the vortex velocity vanishes.

  • A Time of Great Growth
    Newsletter | Spring 2019 A Time of Great Growth Heartfelt greetings from the UC Riverside Department of Physics and Astronomy. This is our annual newsletter, sent out each Spring to stay connected with our former students, retired faculty, and friends in the wider community. The Department continues to grow, not merely in size but also in stature and reputation. For the 2018-2019 academic year, we were pleased to welcome two new faculty: Professors Thomas Kuhlman and Barry Barish. Professor Kuhlman was previously on the faculty at the University of Illinois at Urbana-Champaign. He joins our efforts in the emerging field of biophysics. His research lies in the quantitative imaging and theoretical modeling of biological systems. He works on genome dynamics, quantification of the activity of transposable elements in living cells, and applications to the engineering of genome editing. Professor Barry Barish, who joins us from Caltech, is the winner of the 2017 Nobel Prize in Physics. He brings great prestige to our Department. Along with Professor Richard Schrock of the Department of Chemistry, who also joined UCR in 2018, UCR now has two Nobel Prize winners on its faculty. Professor Barish is an expert on the detection and physics of gravitational waves. He has been one of the key figures in the conception, construction, and operation of the LIGO detector, where gravitational waves were first discovered in 2015, and which led to his Nobel Prize. He is a member of the National Academy of Sciences and the winner of many other prestigious awards. The discovery of gravitational waves is one of the most exciting developments in physics so far this century.

The solitons are found numerically as stationary solutions in the moving frame of a nonlocal Gross Pitaevskii equation and characterized as a function of the key experimental parameters, namely the ratio of the dipolar atomic interactions to the van der Waals interactions, the polarization angle, and the condensate width. The solutions and their integrals of motion are strongly affected by the phonon and roton instabilities of the system. Dipolar matter-wave dark solitons propagate without dispersion and collide elastically away from these instabilities, with the dipolar interactions contributing an additional repulsion or attraction to the soliton-soliton interaction. However, close to the instabilities, the collisions are weakly dissipative. DOI: 10.1103/PhysRevA.93.063617 I.

Wing3 1CERN, Geneva, Switzerland 2Max Planck Institute for Physics, Munich, Germany 3University College London, London, UK 4ETH Zürich, Switzerland 5INR Moscow, Russia 1 Abstract The AWAKE experiment reached all planned milestones during Run 1 (2016-18), notably the demon- stration of strong plasma wakes generated by proton beams and the acceleration of externally injected electrons to multi-GeV energy levels in the proton driven plasma wakefields. During Run 2 (2021 - 2024) AWAKE aims to demonstrate the scalability and the acceleration of elec- trons to high energies while maintaining the beam quality. Within the Physics Beyond Colliders (PBC) study AWAKE++ has explored the feasibility of the AWAKE acceleration scheme for new particle physics experiments at CERN. Assuming continued success of the AWAKE program, AWAKE will be in the position to use the AWAKE scheme for particle physics ap- plications such as fixed target experiments for dark photon searches and also for future electron-proton or electron-ion colliders. With strong support from the accelerator and high energy physics community, these experiments could be installed during CERN LS3; the integration and beam line design show the feasibility of a fixed target experiment in the AWAKE facility, downstream of the AWAKE experiment in the former CNGS area. The expected electrons on target for fixed target experiments exceeds the electrons on target by three to four orders of magnitude with respect to the current NA64 experiment, making it a very promising experiment in the search for new physics.

  • Barry Barish and the Gde: Mission Achievable
    INTERVIEW Barry Barish and the GDE: mission achievable The head of the Global Design Effort for a future International Linear Collider talks about challenges past, present and future. Barry Barish likes a challenge. He admits to a complete tendency to go for the difficult in his research – in his view, life is an adventure. Some might say that his most recent challenge would fit well with a certain famous TV series: “Your mission, should you choose to accept it… is to produce a design for the International Linear Collider that includes a detailed design concept, performance assessments, reliable international costing, an industrialization plan, and siting analysis, as well as detector concepts and scope.” Barish did indeed accept the challenge in March 2005, when he became director of the Global Design Effort (GDE) for a proposed International Linear Collider (ILC). He started in a directorate of one – himself – at the head of a “virtual” laboratory of hundreds of physicists and engineers around the globe. To run the “lab” he has set up a small executive committee, which includes three regional directors (for the Americas, Asia and Europe), three project manag- ers and two leading accelerator experts. There are also boards for R&D, change control and design cost. Barish operates from his base at Caltech, where he has been since 1962 and ultimately became Linde Professor of Physics (now emeri- tus). His taste for research challenges became evident in the 1970s, when he was co-spokesperson with Frank Sciulli (also at Caltech) of the “narrow band” neutrino experiment at Fermilab that studied Barish became director of the Global Design Effort for the International weak neutral currents and the quark substructure of the nucleon.

  • Vibrational Substructure in the OH Stretching Transition of Water and HOD
    9054 J. Phys. Chem. A 2004, 108, 9054-9063 Vibrational Substructure in the OH Stretching Transition of Water and HOD Zhaohui Wang, Andrei Pakoulev, Yoonsoo Pang, and Dana D. Dlott* School of Chemical Sciences, UniVersity of Illinois at Urbana-Champaign, 600 South Mathews AVenue, Urbana, Illinois 61801 ReceiVed: April 2, 2004; In Final Form: August 13, 2004 Ultrafast nonlinear vibrational spectroscopy with mid-IR pumping and incoherent anti-Stokes Raman probing is used to study V)1 excitations of OH stretching (νOH) of water and of HOD in D2O solvent (HOD/D2O). The parent νOH decay and the appearance of daughter stretching and bending excitations are simultaneously monitored, which allows for characterization of the stretch decay pathways. At all times and with all pump frequencies within the νOH band, the excited-state spectrum can be fit by two overlapping subbands, a broader R B red-shifted band νOH and a narrower blue-shifted band νOH. We show these subbands are dynamically distinguishable. They decay with different lifetimes and evidence characteristically different decay pathways. R B ∼ Excitations of the νOH subband generate bending vibrations that νOH does not. The shorter lifetime ( 0.5 ps) R B - of the νOH subband compared to the νOH subband (0.8 0.9 ps) results primarily from enhanced stretch-to- bend anharmonic coupling. The subbands represent persistent structures in the excited state, in that interconversion between subbands (2-10 ps) is slower than excited-state decay. A tentative structural R interpretation is proposed. The νOH subband, on the basis of simulations, its red shift ,and its shorter lifetime, R is proposed to result from strongly hydrogen-bonded “ice-like” water.
