Analytic continuation from imaginary to real chemical potential in two-color QCD

P Cea, L Cosmai, M D'Elia, A Papa - Journal of High Energy …, 2007 - iopscience.iop.org
The method of analytic continuation from imaginary to real chemical potential is one of the
most powerful tools to circumvent the sign problem in lattice QCD. Here we test this method …

Lattice QCD at finite density

C Schmidt - arXiv preprint hep-lat/0610116, 2006 - arxiv.org
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 …

Gluon propagator without lattice Gribov copies on a finer lattice

C Alexandrou, P De Forcrand, E Follana - Physical Review D, 2002 - APS
We extend our study of the gluon propagator in quenched lattice QCD using the Laplacian
gauge to a finer lattice. We verify the existence of a pole mass as we take the continuum limit …

Equation of state at finite density from imaginary chemical potential

T Takaishi, P de Forcrand, A Nakamura - arXiv preprint arXiv:1002.0890, 2010 - arxiv.org
We perform two flavor QCD simulations with an imaginary chemical potential and measure
derivatives of the pressure up to 4th order as a function of the imaginary chemical potential …

Responses of quark condensates to the chemical potential

O Miyamura, S Choe, Y Liu, T Takaishi, A Nakamura - Physical Review D, 2002 - APS
The responses of quark condensates to the chemical potential, as a function of temperature
T and chemical potential μ, are calculated within the Nambu–Jona-Lasinio (NJL) model. We …

Chiral dynamics in QCD at finite chemical potential

S Gupta, R Ray - Physical Review D—Particles, Fields, Gravitation, and …, 2004 - APS
We present the renormalized Taylor expansion of the chiral condensate with chemical
potential. The relation with the Taylor coefficients of meson susceptibilities and the quark …

Chemical potential dependence of chiral quark condensate in Dyson–Schwinger equation approach of QCD

L Chang, H Chen, B Wang, W Yuan, Y Liu - Physics Letters B, 2007 - Elsevier
We propose a chemical potential-dependent effective gluon propagator and study the chiral
quark condensate in strongly interacting matter in the framework of Dyson–Schwinger …

T violation in baryonic B decays

CQ Geng, YK Hsiao - International Journal of Modern Physics A, 2006 - World Scientific
We study T violation in the three-body charmless baryonic decay of through the T-odd triple
product correlation in the standard model. We find that the T violating asymmetry is 10 …

Simulation of Wilson fermion at finite isospin density

A Nakamura, T Takaishi - Nuclear Physics B-Proceedings Supplements, 2004 - Elsevier
For QCD with Wilson fermions at isospin chemical potential we study the finite phase
transition on an 83× 4 lattice at κ= 0.15. We use two gauge actions: Wilson action and DBW2 …
