Multiplicity, probabilities, and canonical sectors for the cold QCD matter
Kouji Kashiwa, Hiroaki Kouno
At sufficiently low temperature, without requiring any numerical data at finite real chemical potential, we can clarify the canonical partition function with fixed quark number via…
Nonanalyticity, sign problem and Polyakov line in Z3-symmetric heavy quark model at low temperature: Phenomenological model analyses
Hiroaki Kouno, Kouji Kashiwa, Takehiro Hirakida
The nonanalyticity and the sign problem in the Z3-symmetric heavy quark model at low temperature are studied phenomenologically. For the free heavy quarks, the nonanalyticity is an…
Persistent homology analysis for dense QCD effective model with heavy quarks
Kouji Kashiwa, Takehiro Hirakida, Hiroaki Kouno
The isospin chemical potential region is known as the sign-problem free region of quantum chromodynamics (QCD). In this paper, we introduce the isospin chemical potential to the th…
Anatomy of the dense QCD matter from canonical sectors
Kouji Kashiwa, Hiroaki Kouno
We investigate the nuclear and the quark matter at finite real chemical potential () and low temperature from the viewpoint of the canonical sectors constructed via t…
A model consistent with LQCD data on -meson screening mass
Masahiro Ishii, Akihisa Miyahara, Hiroaki Kouno +1
Recently, state-of-art LQCD calculations were done for -meson and -meson screening mass, and . We consider the two-flavor system, and…
Information theoretical view of QCD effective model with heavy quarks
Kouji Kashiwa, Hiroaki Kouno
To understand the phase transition phenomena, information theoretical approaches can pick up some important properties of the phenomena based on the probability distribution. In th…
