Lombardo (INFN Firenze) We study the scaling properties of QCD in temperature and mass close to the thermal crossover, and for quark masses ranging from the heavy quark regime to the physical values. The lattice results are obtained in the fixed scale approach, either with anisotropic simulations with Nf = 2 + 1 flavours, and with simulations of Nf = 2 + 1 + 1 flavours at maximal twist. We note that a simple combination of chiral observables reduces the additive renormalizations and the contribution from the regular terms in the equation of state, thus helping the assessment of the hypothesized universal behaviour. Universal scaling close to chiral limit of QCD Anirban Lahiri Speaker: A. Lahiri (Biefefeld U.) Chiral phase transition has been a topic of interest over decades and order of the chiral phase transition has an effect on the global phase diagram of QCD. In this talkI will review some of our recent calculations towards the limit of 2 massless flavors. I shall start with the determination of the chiral transition temperature and then show how our calculation is able to throw some light on the long standing debate about the order of the chiral phase transition. I shall also show that the gluonic observables and conserved charge fluctuations towards the chiral limit, can be well described by the scaling behavior of an energy like observable w.r.t. chiral symmetry. Fluctuations and the QCD phase diagram from functional meth- ods Christian Fischer Speaker: C. Fischer (University of Giessen) We summarise recent theoretical results on the QCD phase diagram and the proper- ties of QCD’s critical point based on a combination of lattice QCD and Dyson-Schwinger equations. Using lattice input for the quenched gluon propagator, our approach correctly reproduced and predicted Nf=2+1 flavour lattice results for the quark condensate

  • Spontaneous Electromagnetic Superconductivity and Superfluidity
    Spontaneous electromagnetic superconductivity and superfluidity of QCD×QED vacuum in strong magnetic field M. N. Chernodub∗† CNRS, Laboratoire de Mathématiques et Physique Théorique, Université François-Rabelais, Fédération Denis Poisson, Parc de Grandmont, 37200 Tours, France Department of Physics and Astronomy, University of Gent, Krijgslaan 281, S9, Gent, Belgium E-mail: [email protected] Jos Van Doorsselaere Department of Physics and Astronomy, University of Gent, Krijgslaan 281, S9, Gent, Belgium E-mail: [email protected] Henri Verschelde Department of Physics and Astronomy, University of Gent, Krijgslaan 281, S9, Gent, Belgium E-mail: [email protected] It was recently shown that the vacuum in the background of a strong enough magnetic field may become an electromagnetic superconductor due to interplay between strong and electromagnetic forces. The superconducting ground state of the QCD×QED sector of the vacuum is associated with magnetic–field–assisted emergence of quark–antiquark condensates which carry quantum numbers of charged r mesons (i.e., of electrically charged vector particles made of lightest, u and d, quarks and antiquarks). Here we demonstrate that this exotic electromagnetic superconduc- tivity of vacuum is also accompanied by even more exotic superfluidity of the neutral r mesons. The superfluid component – despite being electrically neutral – turns out to be sensitive to an external electric field as the superfluid may ballistically be accelerated by a test background elec- tric field along the magnetic–field axis. In the ground state both superconducting and superfluid components are inhomogeneous periodic functions of the transversal (with respect to the axis of the magnetic field) spatial coordinates.

  • Vortices with Magnetic Field Inversion in Noncentrosymmetric
    Vortices with magnetic field inversion in noncentrosymmetric superconductors Julien Garaud,1, ∗ Maxim N. Chernodub,1, 2, y and Dmitri E. Kharzeev3, 4, 5, z 1Institut Denis Poisson CNRS/UMR 7013, Universit´ede Tours, 37200 France 2Pacific Quantum Center, Far Eastern Federal University, Sukhanova 8, Vladivostok, 690950, Russia 3Department of Physics and Astronomy, Stony Brook University, New York 11794-3800, USA 4Department of Physics and RIKEN-BNL Research Center, Brookhaven National Laboratory, Upton, New York 11973, USA 5Le Studium, Loire Valley Institute for Advanced Studies, Tours and Orl´eans,France (Dated: November 30, 2020) Superconducting materials with noncentrosymmetric lattices lacking space inversion symmetry exhibit a variety of interesting parity-breaking phenomena, including the magneto-electric effect, spin-polarized currents, helical states, and the unusual Josephson effect. We demonstrate, within a Ginzburg-Landau framework describing noncentrosymmetric superconductors with O point group symmetry, that vortices can exhibit an inversion of the magnetic field at a certain distance from the vortex core. In stark contrast to conventional superconducting vortices, the magnetic-field reversal in the parity-broken superconductor leads to non-monotonic intervortex forces, and, as a consequence, to the exotic properties of the vortex matter such as the formation of vortex bound states, vortex clusters, and the appearance of metastable vortex/anti-vortex bound states. I. INTRODUCTION noncentrosymmetric superconductors are supercon- ducting materials whose crystal structure is not symmet- ric under the spatial inversion. These parity-breaking materials have attracted much theoretical [1{6] and ex- perimental [7{11] interest, as they make it possible to investigate spontaneous breaking of a continuous sym- metry in a parity-violating medium (for recent reviews, see [12{14]).

  • Vacuum Superconductivity, Conventional Superconductivity and Schwinger Pair Production∗

N. CHERNODUBy CNRS, Laboratoire de Math´ematiqueset Physique Th´eorique,Universit´eFran¸cois-Rabelais, F´ed´eration Denis Poisson - CNRS, Parc de Grandmont, Universit´ede Tours, 37200 France Department of Physics and Astronomy, University of Gent, S9, B-9000 Gent, Belgium E-mail: [email protected] In a background of a very strong magnetic field a quantum vacuum may turn into a new phase characterized by anisotropic electromagnetic superconductivity. The phase tran- 16 sition should take place at a critical magnetic field of the hadronic strength (Bc ≈ 10 2 Tesla or eBc ≈ 0:6 GeV ). The transition occurs due to an interplay between electromag- netic and strong interactions: virtual quark{antiquark pairs popup from the vacuum and create { due to the presence of the intense magnetic field { electrically charged and elec- trically neutral spin-1 condensates with quantum numbers of ρ mesons. The ground state of the new phase is a complicated honeycomblike superposition of superconductor and superfluid vortex lattices surrounded by overlapping charged and neutral condensates. In this talk we discuss similarities and differences between the superconducting state of vacuum and conventional superconductivity, and between the magnetic–field–induced vacuum superconductivity and electric{field{induced Schwinger pair production. Keywords: Quantum Chromodynamics; Strong Magnetic Field; Superconductivity. PACS numbers: 12.38.-t, 13.40.-f, 74.90.+n 1.
