Quantum phase transition in a non-Hermitian XY spin chain with global complex transverse field
Yu-Guo Liu, Lu Xu, Zhi Li
In this work, we investigate the quantum phase transition in a non-Hermitian XY spin chain. The phase diagram shows that the critical points of Ising phase transition expand into a…
