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…
Multiband Topological Heterojunctions on the Surface Nanoscale Axial Photonics Platform
Nathaniel Fried, Dashiell L. P. Vitullo, Avik Dutt
Analogue Hamiltonian simulation (AHS) in photonic systems can be an enticing alternative to direct experimental study of complex Hamiltonian systems as a result of the low cost and…
Quantum Metamorphosis: Programmable Emergence and the Breakdown of Bulk-Edge Dichotomy in Multiscale Systems
Mahmoud Jalali Mehrabad, Alireza Parhizkar, Lida Xu +6
Multiscale synergy -- the interplay of a system's distinct characteristic length, time, and energy scales -- is becoming a unifying thread across many contemporary branches of scie…
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,…
Highly squeezed nanophotonic quantum microcombs with broadband frequency tunability
Yichen Shen, Ping-Yen Hsieh, Dhruv Srinivasan +8
Squeezed light offers genuine quantum advantage in enhanced sensing and quantum computation; yet the level of squeezing or quantum noise reduction generated from nanophotonic chips…
