Mixed-state quantum geometry of dense two-color QCD matter
Kouji Kashiwa, Riki Oshima, Hiroaki Kouno
We investigate an information-geometric approach to dense two-color QCD using thermal states defined as normalized Gibbs states in the two-flavor Nambu--Jona-Lasinio model at the m…

Effective degrees of freedom, trace anomaly and c-theorem like condition in the hadron resonance gas model
Hiroaki Kouno, Riki Oshima, Kouji Kashiwa
The relation between the effective degrees of freedom (EDOF) and the trace anomaly is studied in the hadron resonance gas (HRG) model. If we regard the thermodynamical relation as…

Thermodynamic geometry in hadron resonance gas model at real and imaginary baryon chemical potential and a simple sufficient condition for quark deconfinement
Riki Oshima, Hiroaki Kouno, Motoi Tachibana +1
The thermodynamic geometry of the hadron resonance gas model with (without) excluded volume effects (EVE) of baryons is investigated. The case with imaginary mu, where mu is the ba…
