QCD phase diagram: an overview [PDF]

Proceedings of XXIVth International Symposium on Lattice Field Theory — PoS(LAT2006), 2006
The aim of this review is to summarize the contemporary understanding of the QCD phase diagram as a function of temperature and baryo-chemical potential. The focus is on recent theoretical developments due to lattice simulations of the phase diagram.

A Pedagogical Introduction to the Lifshitz Regime

Universe, 2019
We give an elementary and pedagogical review of the phase diagrams which are possible in quantum chromodynamics (QCD). Herein, emphasis is upon the appearance of a critical endpoint, where disordered and ordered phases meet.

Finite Density QCD: a New Approach

, 2005
We introduce a new approach to analyze the phase diagram of QCD at finite chemical potential and temperature, test it in the Gross-Neveu model at finite baryon density, and apply it to the study of the chemical potential-temperature phase diagram of QCD ...

Testing the criterion for correct convergence in the complex Langevin method

Journal of High Energy Physics, 2018
Recently the complex Langevin method (CLM) has been attracting attention as a solution to the sign problem, which occurs in Monte Carlo calculations when the effective Boltzmann weight is not real positive.

Exploring the QCD Phase Diagram [PDF]

Proceedings of 9th International Workshop on Critical Point and Onset of Deconfinement — PoS(CPOD2014), 2015
In this contribution we will address a few selected topics concerning the search for a phase structure in the QCD phase diagram. We will extract some constraints for model calculations from basic consideration about the QCD phase diagram. We will also discuss to what extent lattice calculations may be compared to measurements, and what the necessary ...

Lattice QCD at Finite Density [PDF]

, 2006
I discuss different approaches to finite density lattice QCD. In particular, I focus on the structure of the phase diagram and discuss attempts to determine the location of the critical end-point.

The phase diagram of QCD

Contemporary Physics, 2001
I use simple thermodynamic reasoning to argue that at temperatures of order a trillion kelvin, QCD, the theory which describes strongly interacting particles such as protons and neutrons under normal conditions, undergoes a phase transition to a plasma of more elementary constituents called quarks and gluons.

Magnetic catalysis and inverse catalysis for heavy pions

Journal of High Energy Physics, 2019
We investigate the QCD phase diagram for nonzero background magnetic fields using first-principles lattice simulations. At the physical point (in terms of quark masses), the thermodynamics of this system is controlled by two opposing effects: magnetic ...

HADES and the QCD phase diagram

Proceedings of The International conference on Critical Point and Onset of Deconfinement — PoS(CPOD2021), 2022
We discuss new experimental results on the mechanisms of light nuclei production, fluctuationsof conserved charges and the emissivity of matter, studied with HADES at SIS18. The multi-differential representations of hadron and dilepton spectra, collective effects and particle correla-tions are confronted with hitherto model calculations.

Lattice QCD Overview [PDF]

EPJ Web of Conferences
I review recent progress in lattice QCD calculations of the QCD phase diagram and equation of state at non-zero temperature and baryochemical potential. I also discuss some connections with heavy ion collisions.
