Roberge-Weiss periodicity and singularity in hadron resonance gas model with excluded volume effects
Riki Oshima, Hiroaki Kouno, Kouji Kashiwa
Quantum chromodynamics (QCD) with pure imaginary baryon number chemical potential mu =i theta T, where T is temperature and theta is a real number, has the Roberge-Weiss periodicit…
Hadron-quark transition and chiral symmetry restoration at high density
Hiroaki Kouno, Kouji Kashiwa
A simple phenomenological hybrid hadron-quark model with effective volume effects of baryons and chiral dynamics is investigated. The hybrid EoS naturally connects the low density…
Application of the path optimization method to a discrete spin system
Kouji Kashiwa, Yusuke Namekawa, Akira Ohnishi +1
The path optimization method, which is proposed to control the sign problem in quantum field theories with continuous degrees of freedom by machine learning, is applied to a spin m…
Instability of holographic cold compact stars with a color superconducting core
Kazuo Ghoroku, Kouji Kashiwa, Yoshimasa Nakano +2
We study a holographic model of quantum chromodynamics, which can describe a color superconductor and a dilute nucleon gas phase. The two phases are adjoined in the phase diagram a…
