$P T$ -like phase transitions from square roots of supersymmetric Hamiltonians

Jacob L. Barnett, Ramy El-Ganainy

We introduce a general framework for realizing $P T$ -like phase transitions in non-Hermitian systems without imposing explicit parity--time ( $P T$ ) symmetry. The…

Heisenberg and Heisenberg-Like Representations via Hilbert Space Bundle Geometry in the Non-Hermitian Regime

Chia-Yi Ju, Adam Miranowicz, Jacob Barnett +2

The equivalence between the Schrödinger and Heisenberg representations is a cornerstone of quantum mechanics. However, this relationship remains unclear in the non-Hermitian regime…
