Non-Hermitian Exceptional Topology on a Klein Bottle Photonic Circuit
Ze-Sheng Xu, J. Lukas K. König, Andrea Cataldo +8
Non-Hermitian physics has unlocked a wealth of unconventional wave phenomena beyond the reach of Hermitian systems, with exceptional points (EPs) driving enhanced sensitivity, nonr…
Emulation of Coherent Absorption of Quantum Light in a Programmable Linear Photonic Circuit
Govind Krishna, Jun Gao, Sam O Brien +5
Non-Hermitian quantum systems, governed by nonunitary evolution, offer powerful tools for manipulating quantum states through engineered loss. A prime example is coherent absorptio…
Floquet-driven light transport in programmable photonic processors via discretized evolution of synthetic magnetic fields
Andrea Cataldo, Rohan Yadgirkar, Ze-Sheng Xu +5
Photons, unlike electrons, do not couple directly to magnetic fields, yet synthetic gauge fields can impart magnetic-like responses and enable directional transport. Discretized Fl…
