Description:
Author(s): C. Li, G. Zhang, X. Z. Zhang, and Z. Song A conventional quantum phase transition (QPT) can be accessed by varying a real parameter at absolute zero temperature. Motivated by the discovery of the pseudo-Hermiticity of non-Hermitian systems, we explore the QPT in the non-Hermitian PT-symmetric Ising model, which is driven by a staggered comp... [Phys. Rev.
