Long-range bipartite entanglement in XXZ spin chains with the exponential and power-law long-range interactions
Na Li, Yang Zhao, Wen-Long Ma +2
Long-range bipartite entanglement (LBE) and its distribution properties are studied in XXZ spin chains with the exponential and power-law long-range interactions (ELRIs and PLRIs).…

Polarization dynamics of the spin-boson model in the shifted boson Hilbert space
Yang Zhao, Lipeng Chen
Faithfully simulating the dynamics of open quantum systems requires efficiently addressing the challenge of an infinite Hilbert space. Inspired by the shifted boson operator techni…

Entropy dynamics of the binary bond disordered Heisenberg chain
Di Han, Yankui Bai, Yang Zhao
In this article, we study the quench dynamics of the binary bond disordered Heisenberg spin chain. First, we develop a new algorithm, the ancilla TEBD method, which combines the pu…
