  1. 530. Mesonic Condensation under a Global Rotation
    Defu Hou (Central China Normal University)
    11/5/19, 11:00 AM
    QCD at finite temperature and baryon density
    Oral Presentation

    Recently there have been rapidly growing interests in understanding the properties and phase structures of matter under extreme fields like magnetic field or global rotation. Examples of such physical systems come from a variety of different areas, such as the hot quark-gluon plasma in peripheral heavy ion collisions, dense nuclear matter in rapidly spinning neutron stars, lattice gauge theory...

  2. 7. Regressive and generative neural networks for scalar field theory
    Kai Zhou (FIAS, Goethe-University Frankfurt am Main)
    11/5/19, 11:20 AM
    QCD at finite temperature and baryon density
    Oral Presentation

    We explore the perspectives of machine learning techniques in the context of quantum field theories. In particular, we discuss two-dimensional complex scalar field theory at nonzero temperature and chemical potential – a theory with a nontrivial phase diagram. A neural network is successfully trained to recognize the different phases of this system and to predict the value of various...

  3. 587. The crossover line in the (T, mu)-phase diagram of QCD
    Jana N. Guenther (University of Wuppertal)
    11/5/19, 11:40 AM
    QCD at finite temperature and baryon density
    Oral Presentation

    An efficient way to study the QCD phase diagram at small finite density
    is to extrapolate thermodynamical observables from imaginary chemical
    potential. The phase diagram features a crossover line starting from the
    transition temperature already determined at zero chemical potential. In
    this talk we focus on the Taylor expansion of this line up to $\mu^4$
    contributions. We present the...

  4. 32. Structure and Signals for a Lifshitz Regime
    Robert Pisarski (Brookhaven National Lab.)
    11/5/19, 12:00 PM
    QCD at finite temperature and baryon density
    Oral Presentation

    In the plane of temperature and chemical potential, QCD may exhibit a Critical End Point (CEP). if a region with spatially inhomogeneous condensates exists, there may also be a Lifshitz Regime, either instead of, or in addition to, a CEP. We study the Lifshitz Regime using both a large N expansion and using numerical simulations at small N. Experimentally, we contrast the fluctuations in...

  5. 393. Spectral functions for hot pions below Tc
    Sourendu Gupta (TIFR)
    11/5/19, 12:20 PM
    QCD at finite temperature and baryon density
    Oral Presentation

    Long-distance properties of QCD are non-perturbative in nature. Lattice computations provide a reliable tool for extracting such information for correlation functions in the space-like domain of momenta, for example for screening phenomena. However, the approach to equilibrium of QCD matter requires knowledge of correlation functions in the time-like domain.
