Implication of Existence of Hybrid stars and Theoretical Expectation of Submillisecond Pulsars

Xiaoping Zheng, Nana Pan, Shuhua Yang +3

We derive the bulk viscous damping timescale of hybrid stars, neutron stars with quark matter core. The r-mode instability windows of the stars show that the theoretical results ar…

Bulk viscosity of Mixed nucleon-hyperon-quark Matter in Neutron stars

Nana Pan, Xiaoping Zheng, Jiarong Li

We calculate the coefficient of bulk viscosity by considering the non-leptonic weak interactions in the cores of hybrid stars with both hyperons and quarks. We first determine the…

The Critical Rotation of Strange Stars and Rapidly Rotating Pulsars

Zheng Xiaoping, Yang Shuhua, Li Jiarong

We utilize the bulk viscosity of interacting strange quark matter to reevaluate the damping time scale. The presence of medium effect of bulk viscosity leads to a stronger damping…

Bulk viscosity of interacting strange quark matter

Zheng Xiaoping, Yang Shuhua, Li Jiarong

The quarks are regarded as quasiparticles, which acquire an effective mass generated by the interaction with the other quarks of the dense system. The bulk viscosity is re-expresse…

Kinetic-theory approach to Gluon Self-energy beyond Hard Thermal Loops

Zheng Xiaoping, Li Jiarong

We compare the effective dynamics of soft fields, based on temperature field theory, with the mean field dynamics from non-Abelian kinetic theory. We derive the polarization tensor…

Covariant Perturbation Theory of Non-Abelian Kinetic Theory

Xiaoping Zheng, Jiarong Li

A double perturbation idea is presented in framework of the quark-gluon plasma kinetic theory. A solvable set of equations from the 'double perturbation' is derived and the equatio…
