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…
Lorentz and CPT Violation in Top-Quark Production
Zhi Liu
Signals for Lorentz and CPT violation can appear in a wide range of experiments including hadron colliders like the LHC. We present a calculation of the Lorentz-violating cross sec…
Lorentz and CPT Violation in Top-Quark Production and Decay
Micheal S. Berger, Alan Kostelecky, Zhi Liu
The prospects are explored for testing Lorentz and CPT symmetry in the top-quark sector. We present the relevant Lagrange density, discuss physical observables, and describe the si…
