Programmable Non-Hermitian Synchronization of Light on a Silicon Photonic Processor
Ze-Sheng Xu, Nan Cheng, Mohammed S. Elmusrati +6
Synchronization is a pervasive collective phenomenon underlying the firing of neurons, the beating of the heart, and the coherent emission of lasers. Across these systems, dissipat…
Bloch Siegert Physics in a Reconfigurable Photonic Binary Lattice
Ze-Sheng Xu, Liwei Duan, Rohan Yadgirkar +4
The Bloch Siegert shift, a hallmark correction arising from counter-rotating interactions in driven two-level systems, has an exact counterpart in binary lattices under static forc…
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…
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…
