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 <i>M</i> is introduced to describe the critical behaviors in the Yang-Lee edge singularity (YLES). The <i>M</i> does not diverge at the YLES point, a be...
