Finite-density lattice QCD and sign problem: Current status and open problems

K Nagata - Progress in Particle and Nuclear Physics, 2022 - Elsevier
Finite-density lattice QCD aims for the first-principle study of QCD at finite density, which
describes the system consisting of many quarks. The main targets are systems such as …

Overview of the QCD phase diagram: Recent progress from the lattice

JN Guenther - The European Physical Journal A, 2021 - Springer
In recent years there has been much progress on the investigation of the QCD phase
diagram with lattice QCD simulations. In this review we focus on the developments in the last …

QCD crossover at finite chemical potential from lattice simulations

S Borsanyi, Z Fodor, JN Guenther, R Kara, SD Katz… - Physical review …, 2020 - APS

The phase diagram of dense QCD

K Fukushima, T Hatsuda - Reports on Progress in Physics, 2010 - iopscience.iop.org
The current status of theoretical studies on the quantum chromodynamics (QCD) phase
diagram at finite temperature and baryon chemical potential is reviewed with special …

The QCD phase diagram from analytic continuation

R Bellwied, S Borsányi, Z Fodor, J Günther, SD Katz… - Physics Letters B, 2015 - Elsevier
We present the crossover line between the quark gluon plasma and the hadron gas phases
for small real chemical potentials. First we determine the effect of imaginary values of the …

Long Range Plan: Dense matter theory for heavy-ion collisions and neutron stars

A Lovato, T Dore, RD Pisarski, B Schenke… - arxiv preprint arxiv …, 2022 - arxiv.org
Since the release of the 2015 Long Range Plan in Nuclear Physics, major events have
occurred that reshaped our understanding of quantum chromodynamics (QCD) and nuclear …

QCD equation of state matched to lattice data and exhibiting a critical point singularity

P Parotto, M Bluhm, D Mroczek, M Nahrgang… - Physical Review C, 2020 - APS
We construct a family of equations of state for QCD in the temperature range 30 MeV≤ T≤
800 MeV and in the chemical potential range 0≤ μ B≤ 450 MeV. These equations of state …

Simulating QCD at finite density

P De Forcrand - arxiv preprint arxiv:1005.0539, 2010 - arxiv.org
In this review, I recall the nature and the inevitability of the" sign problem" which plagues
attempts to simulate lattice QCD at finite baryon density. I present the main approaches used …

The QCD equation of state at finite density from analytical continuation

J Günther, R Bellwied, S Borsanyi… - EPJ Web of …, 2017 - epj-conferences.org
An effcient way to study the QCD phase diagram at small finite density is to extrapolate
thermodynamical observables from imaginary chemical potential. In this talk we present …
