Analytic continuation of finite density QCD with heavy quarks in the strong coupling region
Shinji Ejiri, Hiroshi Yoneyama
Complex nature of finite density QCD with heavy quarks in the strong coupling region is studied. For this purpose, we consider the effective potential as a function of Polyakov lin…
First order transition regions in the quark masses and chemical potential parameter space of QCD
Shinji Ejiri, Norikazu Yamada, Hiroshi Yoneyama
We investigate the phase transitions of (2+Nf)-flavor QCD, where two light flavors and Nf massive flavors exist, aiming to understand the phase structure of (2+1)-flavor QCD. Perfo…
Complex singularities around the QCD critical point at finite densities
Shinji Ejiri, Yasuhiko Shinno, Hiroshi Yoneyama
Partition function zeros provide alternative approach to study phase structure of finite density QCD. The structure of the Lee-Yang edge singularities associated with the zeros in…
Singularities around the QCD critical point in the complex chemical potential plane
Shinji Ejiri, Yasuhiko Shinno, Hiroshi Yoneyama
We consider thermodynamic singularities appearing in the complex chemical potential plane in the vicinity of QCD critical point. In order to investigate what the singularities are…
Singularities of QCD in the complex chemical potential plane
Shinji Ejiri, Hiroshi Yoneyama
We study the thermodynamic singularities of QCD in the complex chemical potential plane by a numerical simulation of lattice QCD, and discuss a method to understand the nature of t…
Analytic Continuation in Two-color Finite Density QCD and Chiral Random Matrix Model
Yasuhiko Shinno, Hiroshi Yoneyama
Two-color finite density QCD is free from the sign problem, and it is thus regarded as a good model to check the validity of the analytic continuation method. We study the method i…
