Entanglement Entropy of the Early Universe in Generalized Chaplygin Gas Model
Pisin Chen, Yuezhen Niu
We provide an explicit calculation of the evolution of the cosmic entanglement entropy in the early universe before the matter dominant era. This is made possible by invoking the g…

Majorana zero modes in a quantum Ising chain with longer-ranged interactions
Yuezhen Niu, Suk Bum Chung, Chen-Hsuan Hsu +3
A one-dimensional Ising model in a transverse field can be mapped onto a system of spinless fermions with p-wave superconductivity. In the weak-coupling BCS regime, it exhibits a z…

Bose and Fermi gases in the early universe with self-gravitational effect
Yuezhen Niu, Junwu Huang, Bo-Qiang Ma
We study the self-gravitational effect on the equation of state (EoS) of Bose and Fermi gases in thermal equilibrium at the end of reheating, the period after quark-hadron transiti…
