Gravitational wave spectrum from first-order QCD phase transitions based on a parity doublet model
Bikai Gao, Jingdong Shao, Hong Mao
We investigate the gravitational wave spectrum from first-order QCD phase transitions using the parity doublet model at finite baryon chemical potential. The model incorporates the…

Suppression of dynamical momentum-space shell by chiral symmetry
Bikai Gao, Michał Marczenko
We investigate the appearance of quark degrees of freedom in dense isospin-symmetric nuclear matter. We employ the parity doublet model to incorporate chiral dynamics. Specifically…

Ferromagnetic instabilities in quarkyonic matter
Bikai Gao, Kenichi Yoshida
We investigate the magnetic properties of quarkyonic matter, which naturally bridges nuclear and quark matter at intermediate densities relevant to neutron star cores. We extend th…
