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-…
Intrinsically chiral exciton polaritons in an atomically-thin semiconductor
Matthias J. Wurdack, Ivan Iorsh, Sarka Vavreckova +15
Photonic bound states in the continuum (BICs) have emerged as a versatile tool for enhancing light-matter interactions by strongly confining light fields. Chiral BICs are photonic…
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…
