Observables in quantum field theory on a collapsing black hole background
Micheal S. Berger, Zhi Liu
We study the quantum radiation from a curved background using scalar observables constructed from the (1+1) dimensional renormalized stress-energy tensor (RSET). We compute energy…

Applicability of Relativistic Point-Coupling Models to Neutron Star Physics
Bao Yuan Sun, Zhi Wei Liu, Ruo Yu Xing
Comparing with a wide range of covariant energy density functional models based on the finite-range meson-exchange representation, the relativistic mean-field models with the zero-…

Correlated structure of nuclear symmetry energy from covariant nucleon self-energy
Zhi Wei Liu, Qian Zhao, Bao Yuan Sun
Based on the Hugenholtz-Van Hove theorem, the symmetry energy and its density slope parameter are decomposed in terms of the nucleon self-energies within the covariant dens…
