Energy-Resolved Eigenmode Spectroscopy of 1-D and 2-D Non-Hermitian Skin Effects

Rohith Srikanth, Sashank Kaushik Sridhar, Avik Dutt

Non-Hermitian lattices can host the non-Hermitian skin effect, a boundary-induced collapse of all bulk eigenstates into exponentially localized edge modes. This effect underlies an…

Toward Chaotic Group Velocity Hopping of an On-Chip Dissipative Kerr Soliton

Gregory Moille, Sashank Kaushik Sridhar, Pradyoth Shandilya +3

Chaos enables randomness-based applications, particularly in photonic systems. Integrated optical frequency combs (microcombs) have previously been observed in either chaotic modul…

Measuring invariants in dimer models and cross-coupled ladders with a programmable photonic molecule

Sashank Kaushik Sridhar, Rohith Srikanth, Alexander R. Miller +2

Topological models are characterized by a quantized topological invariant and provide a description of novel phases of matter that can exhibit localized edge states, corner modes,…
