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…
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…
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…
Roberge-Weiss periodicity, canonical sector and modified Polyakov-loop
Kouji Kashiwa, Hiroaki Kouno
To obtain deeper understanding of QCD properties at finite temperature, we consider the Fourier decomposition of the grand-canonical partition function based on the canonical ensem…
Control the model sign problem via path optimization method: Monte-Carlo approach to QCD effective model with Polyakov loop
Kouji Kashiwa, Yuto Mori, Akira Ohnishi
We apply the path optimization method to a QCD effective model with the Polyakov loop at finite density to circumvent the model sign problem. The Polyakov-loop extended Nambu--Jona…
Anomalous Hall effect in dense QCD matter
Toshitaka Tatsumi, Ryo Yoshiike, Kouji Kashiwa
In this letter, we investigate the anomalous Hall effect in dense QCD matter. When the dual chiral density wave which is the spatially modulated chiral condensate appears in the me…
Holographic Model at Finite Temperature with -chrage density
Kazuo Ghoroku, Akihiro Nakamura, Masanobu Yahiro
We consider a holographic model of QCD at finite temperature with nonzero chemical potentials conjugate to -charge densities. A critical surface of the confinement-deconfinement…
Holographic Model for Mesons at Finite Temperature
Kazuo Ghoroku, Masanobu Yahiro
A holographic model of QCD at finite temperature is proposed and thermal properties for light mesons are examined in terms of this model. We find interesting temperature dependence…
Holographic Model for Hadrons in Deformed AdS5 Background
Kazuo Ghoroku, Nobuhito Maru, Motoi Tachibana +1
Several physical quantities of light hadrons are examined by a new holographic model of QCD, which is the modified version of the one proposed by Erlich et al. defined on AdS…
Beta-functions in Yang-Mills Theory from Non-critical String
Kazuo Ghoroku
The renormalization group equations of the Yang-Mills theory are examined in the non-critical string theory according to the framework of the holography. Under a simple ansatz for…
