Transmission of Near-Resonant Light Through a Dense Slab of Cold Atoms
PHYSICAL REVIEW A 96, 053629 (2017) Transmission of near-resonant light through a dense slab of cold atoms L. Corman,* J. L. Ville, R. Saint-Jalm, M. Aidelsburger,† T. Bienaimé, S. Nascimbène, J. Dalibard, and J. Beugnon‡ Laboratoire Kastler Brossel, Collège de France, CNRS, ENS-PSL Research University, UPMC-Sorbonne Universités, 11 place Marcelin-Berthelot, 75005 Paris, France (Received 30 June 2017; revised manuscript received 4 October 2017; published 27 November 2017) The optical properties of randomly positioned, resonant scatterers is a fundamentally difficult problem to address across a wide range of densities and geometries. We investigate it experimentally using a dense cloud of rubidium atoms probed with near-resonant light. The atoms are confined in a slab geometry with a subwavelength thickness. We probe the optical response of the cloud as its density and hence the strength of the light-induced dipole-dipole interactions are increased. We also describe a theoretical study based on a coupled dipole simulation which is further complemented by a perturbative approach. This model reproduces qualitatively the experimental observation of a saturation of the optical depth, a broadening of the transition, and a blueshift of the resonance. DOI: 10.1103/PhysRevA.96.053629 I. INTRODUCTION than solid-state systems, strong attenuation of the transmission can be observed at resonance. Third, inhomogeneous Doppler The interaction of light with matter is a fundamental broadening can be made negligible using ultracold atomic problem which is relevant for simple systems, such as an atom clouds. Finally, the geometry and the density of the gases strongly coupled to photons [1–3], as well as for complex can be varied over a broad range. -

The Search for Exomoons and the Characterization of Exoplanet Atmospheres
Corso di Laurea Specialistica in Astronomia e Astrofisica The search for exomoons and the characterization of exoplanet atmospheres Relatore interno : dott. Alessandro Melchiorri Relatore esterno : dott.ssa Giovanna Tinetti Candidato: Giammarco Campanella Anno Accademico 2008/2009 The search for exomoons and the characterization of exoplanet atmospheres Giammarco Campanella Dipartimento di Fisica Università degli studi di Roma “La Sapienza” Associate at Department of Physics & Astronomy University College London A thesis submitted for the MSc Degree in Astronomy and Astrophysics September 4th, 2009 Università degli Studi di Roma ―La Sapienza‖ Abstract THE SEARCH FOR EXOMOONS AND THE CHARACTERIZATION OF EXOPLANET ATMOSPHERES by Giammarco Campanella Since planets were first discovered outside our own Solar System in 1992 (around a pulsar) and in 1995 (around a main sequence star), extrasolar planet studies have become one of the most dynamic research fields in astronomy. Our knowledge of extrasolar planets has grown exponentially, from our understanding of their formation and evolution to the development of different methods to detect them. Now that more than 370 exoplanets have been discovered, focus has moved from finding planets to characterise these alien worlds. As well as detecting the atmospheres of these exoplanets, part of the characterisation process undoubtedly involves the search for extrasolar moons. The structure of the thesis is as follows. In Chapter 1 an historical background is provided and some general aspects about ongoing situation in the research field of extrasolar planets are shown. In Chapter 2, various detection techniques such as radial velocity, microlensing, astrometry, circumstellar disks, pulsar timing and magnetospheric emission are described. A special emphasis is given to the transit photometry technique and to the two already operational transit space missions, CoRoT and Kepler. -

Shining Light Through the Higgs Portal with $\Gamma\Gamma $ Colliders

We study the sensitivity of a high-energy γγ collider to the Higgs portal scenario to a hidden sector above the invisible Higgs decay threshold. We show that such γγ collisions could allow to probe the existence of dark sectors through the Higgs portal comparatively more precisely than any other planned collider facility, from the unique combination of sizable cross-section with clean final state and collider environment. In addition, this search could cover the singlet Higgs portal parameter space yielding a first-order electroweak phase transition in the early Universe. + − p I. Introduction.

The Early Works of Maria Nordman by Laura Margaret
In Situ and On Location: The Early Works of Maria Nordman by Laura Margaret Richard A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in History of Art and the Designated Emphasis in Film Studies in the Graduate Division of the University of California, Berkeley Committee in charge: Associate Professor Julia Bryan-Wilson, Chair Professor Whitney Davis Professor Shannon Jackson Associate Professor Jeffrey Skoller Summer 2015 Abstract In Situ and On Location: The Early Works of Maria Nordman by Laura Margaret Richard Doctor of Philosophy in History of Art and the Designated Emphasis in Film Studies University of California, Berkeley Associate Professor Julia Bryan-Wilson, Chair This dissertation begins with Maria Nordman’s early forays into capturing time and space through photography, film, and performance and it arrives at the dozen important room works she constructed between 1969 and 1979. For these spaces in Southern California, the San Francisco Bay Area, Italy, and Germany, the artist manipulated architecture to train sunshine into specific spatial effects. Hard to describe and even harder to illustrate, Nordman’s works elude definition and definitiveness, yet they remain very specific in their conception and depend on precision for their execution. Many of these rooms were constructed within museums, but just as many took place in her studio and in other storefronts in the working-class neighborhoods of Los Angeles, San Francisco, Milan, Genoa, Kassel, and Düsseldorf. If not truly outside of the art system then at least on its fringes, these works were premised physically and conceptually on their location in the city. -

Laser & Photonics Reviews, October 25, 2018 1 Abstract The increasing level of experimental control over atomic and optical systems gained in the past years have paved the way for the exploration of new physical regimes in quantum optics and atomic physics, characterised by the appearance of quantum many-body phenomena, originally encountered only in condensed-matter physics, and the possibility of experimen- tally accessing them in a more controlled manner. In this review article we survey recent theoretical studies concerning the use of cavity quantum electrodynamics to create quantum many- body systems. Based on recent experimental progress in the fabrication of arrays of interacting micro-cavities and on their coupling to atomic-like structures in several different physical architectures, we review proposals on the realisation of paradig- matic many-body models in such systems, such as the Bose- Crystal light: Photons (yellow) that ordinarily move freely Hubbard and the anisotropic Heisenberg models.

Analyzing photon-count heralded entanglement generation between solid-state spin qubits by decomposing the master equation dynamics Stephen C. Wein,1, ∗ Jia-Wei Ji,1 Yu-Feng Wu,1 Faezeh Kimiaee Asadi,1 Roohollah Ghobadi,1 and Christoph Simon1, y 1Institute for Quantum Science and Technology, and Department of Physics & Astronomy, University of Calgary, 2500 University Drive NW, Calgary, Alberta T2N 1N4, Canada We analyze and compare three different schemes that can be used to generate entanglement between spin qubits in optically-active single solid-state quantum systems. Each scheme is based on first generating entanglement between the spin degree of freedom and either the photon number, the time bin, or the polarization degree of freedom of photons emitted by the systems. We compute the time evolution of the entanglement generation process by decomposing the dynamics of a Markovian master equation into a set of propagation superoperators conditioned on the cumulative detector photon count. We then use the conditional density operator solutions to compute the efficiency and fidelity of the final spin-spin entangled state while accounting for spin decoherence, optical pure dephasing, spectral diffusion, photon loss, phase errors, detector dark counts, and detector photon number resolution limitations. We find that the limit to fidelity for each scheme is restricted by the mean wavepacket overlap of photons from each source, but that these bounds are different for each scheme. We also compare the performance of each scheme as a function of the distance between spin qubits. I. INTRODUCTION The two most critical figures of merit for entanglement generation are efficiency and fidelity. -
Observation of Ultraslow Group Velocity of Light in a Solid
Observation of Ultraslow Group Velocity of Light in a Solid A.V. Turukhin1, V.S. Sudarshanam, and M. S. Shahriar Research Laboratory of Electronics, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, MA 02139 J. A. Musser Texas A&M University, College Station, TX 77843 P.R. Hemmer Air Force Research Laboratory, Sensors Directorate, Hanscom AFB, MA 01731 Abstract: We report ultraslow group velocities of light in a solid. Light speeds as slow as 45 m/s were observed, corresponding to a group delay of 66 ms in a 3-mm thick crystal. Reduction of the group velocity is accomplished by using a sharp spectral feature in absorption and dispersion, produced by a Raman excited spin coherence in an optically dense Pr doped Y2SiO5 crystal. PACS numbers: 42.50.-p, 42.50.Gy, 42.62.Fi 1 Corresponding author: Phone: 617-253-3072 Fax: 801-469-1832 Email: [email protected] 1 Since the first observation of ultraslow light1, there has been substantial interest in its potential applications. For example, it was proposed that slowing the group velocity of a laser pulse down to the speed of sound in a material can produce strong coupling between acoustic waves and the electromagnetic field2. The resultant giant nonlinearity obtained by this method might be utilized for efficient multi-wave mixing and quantum nondemolition measurements3, as well as for novel acousto-optical devices. A carefully controlled, slow group velocity of light might even allow a very efficient nonlinear interaction between laser pulses of extremely low (down to a single photon) energy4. These effects can be used to create quantum entanglement between single photons without an ultrahigh finesse cavity and therefore are of great interest for quantum information processing.
