Hidden continuous quantum phase transition without gap closing in non-Hermitian transverse Ising model

Continuous phase transition in quantum matters is a significant issue in condensed matter physics. In general, the continuous quantum phase transitions in many-body systems occur with gap closing. On the other hand, non-Hermitian systems could display quite different properties as their Hermitian co...
