Momentum-space non-Hermitian skin effect in an exciton-polariton system
Yow-Ming, Hu, Mateusz Król +11
Localization of a macroscopic number of eigenstates on a real-space boundary, known as the non-Hermitian skin effect, is one of the striking topological features emerging from non-…

Zitterbewegung Effect and Quantum Geometry in Non-Hermitian Exciton-Polariton Systems
Yow-Ming Robin Hu, Elena A. Ostrovskaya, Eliezer Estrecho
In this work, we analytically derive a semi-classical equation of motion describing the zitterbewegung effects arising in the dynamics of wavepackets in non-Hermitian systems. In H…

Emergent momentum-space topological pseudospin defects in non-Hermitian systems
Yow-Ming Robin Hu, Elena A. Ostrovskaya, Alexander Yakimenko +1
Topological defects are central to modern physics, from spintronics to photonics, due to their robustness and potential application in information processing. In this work, we disc…
