Single-Mode Laser Arrays with Size-Invariant Loss Discrimination
Wenwen Liu, Shuang Zhang
In conventional coupled oscillator lattices and laser arrays, expanding the active volume inevitably causes spectral crowding and degrades spatial uniformity, posing a long-standin…
Gauge-Engineered Tunable Mode Selection in Non-Hermitian Directed-Graph Networks
Wenwen Liu, Zhang Shuang
Programmable mode selection is essential for integrated photonic networks, yet selectively isolating individual modes without delicate balancing of gain and loss remains challengin…
Quantized decay charges in non-Hermitian networks characterized by directed graphs
Wenwen Liu, Junyao Wu, Li Zhang +6
Non-Hermitian physics has unveiled a realm of exotic phenomena absent in Hermitian systems, with the non-Hermitian skin effect (NHSE) showcasing boundary-localized eigenstates driv…
Boundary-Driven Complex Brillouin Zone in Non-Hermitian Electric Circuits
Yung Kim, Sonu Verma, Minwook Kyung +5
Complex-valued physical quantities, often non-conserved, represent key phenomena in non-Hermitian systems such as dissipation and localization. Recent advancements in non-Hermitian…
