Spontaneous symmetry emergence in a Hermitian system of coupled oscillators without symmetry
T. T. Sergeev, E. S. Andrianov, A. A. Zyablovsky
Spontaneous symmetry breaking in systems with symmetry is a cornerstone phenomenon accompanying second-order phase transitions. Here, we predict the opposite phenomenon, namely, sp…

Signature of exceptional point phase transition in Hermitian systems
T. T. Sergeev, A. A. Zyablovsky, E. S. Andrianov +1
Exceptional point (EP) is a spectral singularity in non-Hermitian systems. The passing over the EP leads to a phase transition, which endows the system with unconventional features…
