Important progress in understanding the behavior of hadronic matter at high density has been achieved recently, by adapting the techniques of condensed matter theory. At asymptotic densities, the combination of asymptotic freedom and BCS theory make a rigorous analysis possible. New phases of matter with remarkable properties are predicted. They provide a theoretical laboratory within which chiral symmetry breaking and confinement can be studied at weak coupling. They may also play a role in…

The Pressure of QCD at Finite Temperature and Quark Number Density
When ordinary hadronic matter composed of e.g. protons and neutrons is subjected to extremely hot or dense conditions, it undergoes a phase transition into quark-gluon plasma (QGP), a new phase of
The phase structure of QCD
We review recent results on the phase structure of QCD and bulk QCD thermodynamics. In particular we discuss how universal critical scaling related to spontaneous breaking of the chiral symmetry
Quasiparticle description of the QCD plasma, comparison with lattice results at finite T and mu
We compare our 2+1 flavor, staggered QCD lattice results with a quasiparticle picture. We determine the pressure, the energy density, the baryon density, the speed of sound and the thermal masses as
We provide a brief introduction to the high density effective theory of QCD. As an application, we consider the instanton correction to the perturbatively generated gap in the color superconducting
Constraining low-energy models of QCD from fundamental interactions
In this work we investigate the phase transitions in QCD at finite chemical potential. We analyze the fixed-point structure of 4-fermion interactions in 2-flavor QCD and show that there appears to be
The phase diagram of dense QCD
The current status of theoretical studies on the quantum chromodynamics (QCD) phase diagram at finite temperature and baryon chemical potential is reviewed with special emphasis on the origin of
Exploring phases of dense QCD with compact stars
I review a number of recent developments in the physics of compact stars containing deconfined quark matter, including (a) their cooling with possible phase transition from a fully gapped to a
Lattice QCD at finite density: A Primer
QCD at finite density presents specific challenges to lattice gauge theory. Nonetheless, a region of the QCD phase diagram up to moderately large baryon chemical potentials has been successfully
Thermodynamics of strong-interaction matter from Lattice QCD
We review results from lattice QCD calculations on the thermodynamics of strong-interaction matter with emphasis on input these calculations can provide to the exploration of the phase diagram and
Lattice QCD at finite temperature and density
Abstract. 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
