Entanglement entropy of a three-spin interacting spin chain with a time-reversal breaking impurity at one boundary
Tanay Nag, Atanu Rajak
We investigate the effect of a time-reversal breaking impurity term on both the equilibrium and non-equilibrium critical properties of entanglement entropy (EE) in a three-spin int…

Complete characterization of spin chains with two Ising symmetries
Bat-el Friedman, Atanu Rajak, Emanuele G. Dalla Torre
Spin chains with two Ising symmetries are the Jordan-Wigner duals of one-dimensional interacting fermions with particle-hole and time-reversal symmetry. From earlier works on Major…
