-like phase transitions from square roots of supersymmetric Hamiltonians
Jacob L. Barnett, Ramy El-Ganainy
We introduce a general framework for realizing -like phase transitions in non-Hermitian systems without imposing explicit parity--time () symmetry. The…

Non-Hermitian Dynamics in Quantum Anomalous Hall Insulators
Le Yi, Emma Steinebronn, Asmaul Smitha Rashid +4
Magnetically doped topological insulators (TIs) exhibit two distinct phases: the quantum anomalous Hall (QAH) phase when the Fermi level resides within the surface gap, and a metal…

A topological route to engineering robust and bright supersymmetric laser arrays
Soujanya Datta, Mohammadmahdi Alizadeh, Ramy El-Ganainy +1
In recent years, several proposals that leverage principles from condensed matter and high-energy physics for engineering laser arrays have been put forward. The most important amo…
