Lattice QCD at Finite Temperature and Density
1.1. Preface There are many reasons to study a complicated interacting field theory like QCD under extreme conditions, eg. at finite temperature and/or nonvanishing baryon number density. Of course, first of all we learn about the collective behaviour of strongly interacting matter, its critical behaviour, equation of state and thermal properties of hadrons as well as their fate at high tempera...
متن کاملLattice QCD at finite temperature and density
QCD at finite temperature and density is becoming increasingly important for various experimental programmes, ranging from heavy ion physics to astro-particle physics. The non-perturbative nature of non-abelian quantum field theories at finite temperature leaves lattice QCD as the only tool by which we may hope to come to reliable predictions from first principles. This requires careful extrapo...
متن کاملLattice QCD at Finite Temperature and Density
A general introduction into the subject aimed at a general theoretical physics audience. We introduce the sign problem posed by finite density lattice QCD, and we discuss the main methods proposed to circumvent it, with emphasis on the imaginary chemical potential approach. The interrelation between Taylor expansion and analytic continuation from imaginary chemical potential is discussed in det...
متن کاملScreening at finite temperature and density
We present lattice QCD results on heavy quark free energies, extract from its temperature dependence entropy and internal energy contributions, and discuss the onset of medium effects that lead to screening of static quark-antiquark sources in a thermal medium. Most results are obtained in (2+1)-flavour QCD on a line of constant physics with almost realistic quark masses and compared to previou...
متن کاملGauge model at finite temperature with massive quarks and at finite density on anisotropic lattice
In the previous paper [1] we considered the pure gluon sector of QCD at finite temperature on lattice with the anisotropy ξ ≡ aσ/aτ 6= 1 [where aσ(aτ ) is the spatial (temporal) spacing]. At present the use of anisotropic lattices ξ >> 1 becomes a very popular technique [2]. In this paper we include matter fields into the consideration. The approximation SU(N) ≃ Z(N) used here does not cover al...
