Purely quadratic non-Gaussianity from tachyonic instability: Primordial black holes and scalar-induced gravitational waves
He-Xu Zhang, Mei Huang
We investigate primordial black hole (PBH) formation in a cosmological scenario where curvature perturbations follow purely quadratic non-Gaussianity, ,…

Chromomagnetic condensation and perturbative confinement induced by imaginary rotation in SU(2) Yang-Mills Theory
Lei Zhang, Kun Xu, Mei Huang
We perturbatively investigate the rotation effect on the Polyakov loop potential in SU(2) gauge theroy within a chromomagnetic background. It is observed that the imaginary rotatio…

The -term effects on isospin asymmetric hot and dense quark matter
Lei Zhang, Lu-Meng Liu, Mei Huang
We investigate the impact of the CP-violating term on isospin symmetry breaking in quark matter and compact star properties using a two-flavor Nambu-Jona-Lasinio (NJL) model. B…
