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…
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…
Sign problem and MEM in lattice field theory with the term
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
Lattice field theory with the term suffers from the sign problem. The sign problem appears as flattening of the free energy. As an alternative to the conventional method, the F…
Sign problem and MEM
Masahiro Imachi, Yasuhiko Shinno, Hiroshi Yoneyama
The sign problem is notorious in Monte Carlo simulations of lattice QCD with the finite density, lattice field theory (LFT) with a term and quantum spin models. In this report,…
The -term, CP Model and the Inversion Approach in the Imaginary Method
Masahiro Imachi, Hitoshi Kambayashi, Yasuhiko Shinno +1
The weak coupling region of CP lattice field theory with the -term is investigated. Both the usual real theta method and the imaginary theta method are studied. The latt…
