Finite-temperature field theory
Joseph I. Kapusta,P.V. Landshoff +1 more
TL;DR: In this article, two Lagrange multipliers are introduced, beta = 1/kT and mu the chemical potential, for discussing the thermodynamics of a quantum field theory one uses the grand canonical formalism: the entropy S is maximised, keeping fixed the ensemble averages E and N of energy and particle number is not conserved.
Book
Finite-Temperature Field Theory: Principles and Applications
Joseph I. Kapusta,Charles Gale +1 more
TL;DR: The 2006 second edition of this book as mentioned in this paper develops the basic formalism and theoretical techniques for studying relativistic quantum field theory at high temperature and density, including functional integral representation of the partition function, diagrammatic expansions, linear response theory, screening and plasma oscillations, spontaneous symmetry breaking, Goldstone theorem, resummation and hard thermal loops, lattice gauge theory, phase transitions, nucleation theory, quark-gluon plasma, and color superconductivity.
Journal ArticleDOI
Quantum chromodynamics at high temperature
TL;DR: In this article, the thermodynamic potential of quantum chromodynamics is calculated in order 1, α c and α c 3 2, where αc is a function of the temperature and chemical potentials.
Journal ArticleDOI
High-energy photons from quark-gluon plasma versus hot hadronic gas
TL;DR: Comparing the thermal emission rates at a temperature $T=200$ MeV it is concluded that the hadron gas shines just as brightly as the quark-gluon plasma.
Journal ArticleDOI
Strongly interacting low-viscosity matter created in relativistic nuclear collisions.
TL;DR: It is shown that the transition from hadrons to quarks and gluons has behavior similar to helium, nitrogen, and water at and near their phase transitions in the ratio eta/s, and suggests that experimental measurements can pinpoint the location of this transition or rapid crossover in QCD.
