Pseudo-Yang-Lee Edge Singularity Critical Behavior in a Non-Hermitian Ising Model
The quantum phase transition of a one-dimensional transverse field Ising model in an imaginary longitudinal field is studied. A new order parameter M is introduced to describe the critical behaviors in the Yang-Lee edge singularity (YLES). The M does not diverge at the YLES point, a behavior differe...
