"Latent heat" of first-order varying pressure transitions
Zheng Xiaoping, Zhang Li, Zhou Xia +1
We consider the energy release associated with first-order transition by Gibbs construction and present such energy release as an accumulation of a series of tiny binding energy di…
Running coupling constant from lattice data and bulk viscosity of strange quark matter
Zheng Xiaoping, Kang Miao, Liu Xuewen +1
We study the bulk viscosity of strange quark matter (SQM) in a quasiparticle model at finite chemical potential by extrapolating the previous quasiparticle model of finite temperat…
An Astronomical Evidence of Existence of Quark Matter and the Prediction for Submillisecond Pulsars
Zheng Xiaoping, Pan Nana, Yang Shuhua +2
We derive the bulk viscous time scale of neutron stars with quark matter core, i.e. hybrid stars. The r-mode instability windows of the stars show the theoretical result accords wi…
Bulk viscosity of strange quark matter in density-dependent quark mass model and dissipation of r-modes in strange stars
Zheng Xiaoping, Liu Xuewen, Kang Miao +1
We study the bulk viscosity of strange quark matter(SQM) in density dependent quark mass model(DDQM) under the background of self-consistent thermodynamics. The correct formulae, w…
