Statistical repulsion on hyperons in two-color dense QCD
Masato Nagatsuka, Toru Kojo
We investigate the onset of hyperons in baryonic (diquark) matter in two-color QCD (QCD) by introducing heavy quark doublets that emulate strange quarks. An even number of flav…

Thermal quarks and Polyakov loops in two-color dense QCD
Yugo Kurebayashi, Toru Kojo, Daiki Suenaga
We study confinement and deconfinement in dense two color QCD by analyzing the dynamics of thermal quarks and gluons. The Polyakov loop is used as a probe of the relevant thermal e…

Tripling Fluctuations and Peaked Sound Speed in Fermionic Matter
Hiroyuki Tajima, Kei Iida, Toru Kojo +1
A crossover involving three-fermion clusters is relevant to the hadron-quark crossover, which, if occurring in a neutron star, could naturally reproduce the dense-matter equation o…
