Emergence of Imaginary Time Crystals in the non-Hermitian Su-Schrieffer-Heeger model
E. Slootman, L. Eek, C. Morais Smith +1
Parity-time symmetry constrains the spectrum of non-Hermitian systems to be either real or come in complex conjugate pairs. The transition between a symmetry-preserving phase with…

Thermodynamics and entanglement entropy of the non-Hermitian SSH model
D. F. Munoz-Arboleda, R. Arouca, C. Morais Smith
Topological phase transitions are found in a variety of systems and were shown to be deeply related with a thermodynamic description through scaling relations. Here, we investigate…
