Exploring the limit of the Lattice-Bisognano-Wichmann form describing the Entanglement Hamiltonian: A quantum Monte Carlo study
Siyi Yang, Yi-Ming Ding, Zheng Yan
As a powerful theoretical construct, the entanglement Hamiltonian (EH) encapsulates the essential entanglement properties of a quantum many-body system. From the EH, one can extrac…

Sudden change in entanglement Hamiltonian: Phase diagram of an Ising entanglement Hamiltonian
Zhe Wang, Siyi Yang, Bin-Bin Mao +2
The form of the entanglement Hamiltonian varies with the parameters of the original system. Whether there is a singularity is the key problem for demonstrating/negating the univers…
