Experimental observation of the Yang-Lee quantum criticality in open systems
Huixia Gao, Kunkun Wang, Lei Xiao +6
The Yang-Lee edge singularity was originally studied from the standpoint of mathematical foundations of phase transitions, and its physical demonstration has been of active interes…

Embedding the Yang-Lee Quantum Criticality in Open Quantum Systems
Norifumi Matsumoto, Masaya Nakagawa, Masahito Ueda
The Yang-Lee edge singularity is a quintessential nonunitary critical phenomenon accompanied by anomalous scaling laws. However, an imaginary magnetic field involved in this critic…

Continuous Phase Transition without Gap Closing in Non-Hermitian Quantum Many-Body Systems
Norifumi Matsumoto, Kohei Kawabata, Yuto Ashida +2
Contrary to the conventional wisdom in Hermitian systems, a continuous quantum phase transition between gapped phases is shown to occur without closing the energy gap in non-He…
