QCD and instantons at finite temperature
The current understanding of the behavior of quantum chromodynamics at finite temperature is presented. Perturbative methods are used to explore the high-temperature dynamics. At sufficiently high
Remarks on the Chiral Phase Transition in Chromodynamics
The phase transition restoring chiral symmetry at finite temperatures is considered in a linear $\ensuremath{\sigma}$ model. For three or more massless flavors, the perturbative
Soft amplitudes in hot gauge theories: A general analysis
Abstract A systematic method for the calculation of amplitudes in hot gauge theories is developed. It is necessary to distinguish between hard momenta (of order T ) and soft momenta (of order gT ).
High-temperature Yang-Mills theories and three-dimensional quantum chromodynamics
We demonstrate that for sufficiently high temperature T the behavior of any four-dimensional gauge theory with small coupling constant a, at distances beyond the electrical Debye screening length
Phases of Cold, Dense Quarks at Large N_c
We consider QCD at nonzero temperature and quark density in the limit of a large number of colors, N_c. We suggest that several distinct phases can arise. Two are familiar: a cold phase of confined
Possibility of spontaneous parity violation in hot QCD
We argue that for QCD in the limit of a large number of colors, the axial $\mathrm{U}(1)$ symmetry of massless quarks is effectively restored at the deconfining phase transition. If this transition
Chiral-symmetry breaking in three-dimensional electrodynamics
When there are many flavors of massless fermions, both three-dimensional electrodynamics, and a supersymmetric variant thereof, each spontaneously break chiral symmetry. For the latter, this occurs
Hadron production in ultra-relativistic nuclear collisions: Quarkyonic matter and a triple point in the phase diagram of QCD
We argue that features of hadron production in relativistic nuclear collisions, mainly at CERN-SPS energies, may be explained by the existence of three forms of matter: Hadronic Matter, Quarkyonic
Fuzzy Bags and Wilson Lines
I start with an elementary observation about the pressure in the deconfined phase of a SU(3) gauge theory without quarks. This suggests a ``fuzzy'' bag model for the analogous pressure in QCD, with
Quark gluon plasma as a condensate of SU(3) Wilson lines
Effective theories for the thermal Wilson line are constructed in an SU(N) gauge theory at nonzero temperature. I propose that the order of the deconfining phase transition for Z(N) Wilson lines is
