Transasymptotics and hydrodynamization of the Fokker-Planck equation for gluons
A. Behtash, S. Kamata, M. Martinez +2
We investigate the non-linear transport processes and hydrodynamization of a system of gluons undergoing longitudinal boost-invariant expansion. The dynamics is described within th…
Critical behavior of the bulk viscosity in QCD
Mauricio Martinez, Thomas Schaefer, Vladimir Skokov
We study the behavior of the bulk viscosity in QCD near a possible critical endpoint in the phase diagram. We verify the expectation that , where …
QCD equation of state matched to lattice data and exhibiting a critical point singularity
Paolo Parotto, Marcus Bluhm, Debora Mroczek +6
We construct a family of equations of state for QCD in the temperature range 30 MeV 800 MeV and in the chemical potential range 450 MeV. These equatio…
Roundtable: What can we learn about confinement and anomalous effects in QCD using analog systems?
M. Cristina Diamantini, Dmitri E. Kharzeev, Alexander Molochkov +2
We discuss a number of examples for recent connections between emergent phenomena in many-body systems in atomic and condensed matter physics, and confinement and other non-perturb…
Euclidean Correlation Functions in a Holographic Model of QCD
Thomas Schaefer
We compute euclidean coordinate space correlation functions in a holographic model of QCD. We concentrate, in particular, on channels that are related to the U(1)_A problem, the fl…
Color superconductivity in dense quark matter
Mark G. Alford, Krishna Rajagopal, Thomas Schaefer +1
Matter at high density and low temperature is expected to be a color superconductor, which is a degenerate Fermi gas of quarks with a condensate of Cooper pairs near the Fermi surf…
What atomic liquids can teach us about quark liquids
Thomas Schaefer
We discuss some aspects of cold atomic Fermi gases in the unitarity limit that are of interest in connection with the physics of quark matter and the quark gluon plasma. We conside…
Goldstone boson currents in a kaon condensed CFL phase
Andreas Gerhold, Thomas Schaefer, Andrei Kryjevski
We study the stability of the kaon condensed color-flavor locked (CFL) phase of dense quark matter with regard to the formation of a non-zero Goldstone boson current. In the kaon c…
Non-Fermi Liquid Effective Field Theory of Dense QCD Matter
Thomas Schaefer
We review an effective field theory for the non-Fermi liquid regime of dense QCD matter. Non-Fermi liquid effects arise due the presence of unscreened magnetic gluon exchanges. We…
The Kohn-Luttinger Effect in Gauge Theories
Thomas Schaefer
Kohn and Luttinger showed that a many body system of fermions interacting via short range forces becomes superfluid even if the interaction is repulsive in all partial waves. In ga…
Fermionic Quasiparticles in QCD at High Baryon Density
Thomas Schaefer
We study fermionic quasi-particles in QCD at very high baryon density. In the normal quark matter phase unscreened magnetic gluon exchanges lead to non-Fermi liquid behavior. Non-F…
Phases of QCD
Thomas Schaefer
In these lectures we provide an introduction to the phase structure of QCD. We begin with a brief discussion of QCD, the symmetries of QCD, and what we mean by a ``phase of QCD''.…
An Effective Theory for Baryons in the CFL Phase
Andrei Kryjevski, Thomas Schaefer
We study the effective field theory for fermions in the color-flavor locked (CFL) phase of high density QCD. The effective theory contains a flavor nonet of baryons interacting wit…
Non-Fermi Liquid Effects in QCD at High Density
Thomas Schaefer, Kai Schwenzer
We study non-Fermi liquid effects due to the exchange of unscreened magnetic gluons in high density QCD by using an effective field theory. A one-loop calculation gives the well kn…
Instantons and the Spin of the Nucleon
T. Schaefer, V. Zetocha
Motivated by measurements of the flavor singlet axial coupling constant of the nucleon in polarized deep inelastic scattering we study the contribution of instantons to OZI violati…
Loops and Power Counting in the High Density Effective Field Theory
Thomas Schaefer
We introduce the high density effective theory of QCD. We discuss, in particular, the problem of developing a consistent power counting scheme.
Instantons and Scalar Multiquark States: From Small to Large N_c
Thomas Schaefer
We study scalar quark-anti-quark and two-quark-two-anti-quark correlation functions in the instanton liquid model. We show that the instanton liquid supports a light scalar-isoscal…
Instanton contribution to scalar charmonium and glueball decays
Valeriu Zetocha, Thomas Schaefer
We study instanton contributions to hadronic decays of the scalar glueball, the pseudoscalar charmonium state , and the scalar charmonium state . Hadronic decays of the $…
Color superconductivity in dense quark matter
M. Alford
I discuss recent developments in our understanding of the color-superconducting phases of cold, dense quark matter. I describe the phase diagram as a function of density and the st…
Can hadrons survive the chiral phase transition ?
T. Schaefer, E. V. Shuryak
We study mesonic and baryonic correlation functions in the temporal directions in the vicinity of the critical temperature using the instanton liquid model. In this m…
