Page Curve from Non-Markovianity
Kaixiang Su, Pengfei Zhang, Hui Zhai
In this letter, we use the exactly solvable Sachdev-Ye-Kitaev model to address the issue of entropy dynamics when an interacting quantum system is coupled to a non-Markovian enviro…

Quench dynamics of entanglement spectrum and topological superconducting phases in a long-range Hamiltonian
Kaixiang Su, Zheng-Hang Sun, Heng Fan
We study the quench dynamics of entanglement spectra in the Kitaev chain with variable-range pairing quantified by power-law decay rate . Considering the post-quench Hamiltonian…
