Taming the pion condensation in QCD at finite baryon density
Shinya Aoki, Masanori Hanada, Atsushi Nakamura
In the Monte Carlo study of QCD at finite baryon density based upon the phase reweighting method, the pion condensation in the phase-quenched theory and associated zero-mode preven…
Testing volume independence of SU(N) pure gauge theories at large N
Antonio Gonzalez-Arroyo, Masanori Okawa
In this paper we present our results concerning the dependence of Wilson loop expectation values on the size of the lattice and the rank of the SU(N) gauge group. This allows to te…
Lee-Yang zero distribution of high temperature QCD and Roberge-Weiss phase transition
Keitaro Nagata, Kouji Kashiwa, Atsushi Nakamura +1
Canonical partition functions and Lee-Yang zeros of QCD at finite density and high temperature are studied. Recent lattice simulations have confirmed that the free energy of QCD is…
Fixed-scale approach to finite-temperature lattice QCD with shifted boundaries
Takashi Umeda
We study the thermodynamics of the SU(3) gauge theory using the fixed-scale approach with shifted boundary conditions. The fixed-scale approach can reduce the numerical cost of the…
