Phase and Photon Number Dependent NOON State Localization in Flat Band Lattices
Rishav Hui, Trideb Shit, Marco Di Liberto +2
Flat-band lattices supporting compact localized states provide a versatile platform for exploring unconventional transport phenomena in photonic, ultracold atomic, electronic, and…
Observation of Unidirectional s-p Orbital Topological Edge States in Driven Photonic Lattices
Gayathry Rajeevan, Sebabrata Mukherjee
Time-periodic modulation of a static system is a powerful method for realizing robust unidirectional topological states. So far, all such realizations have been based on interactio…
Probing the Topological Anderson Transition in Quasiperiodic Photonic Lattices via Chiral Displacement and Wavelength Tuning
Abhinav Sinha, Trideb Shit, Avinash Tetarwal +2
The interplay of topology and disorder in quantum dynamics has recently attracted significant attention across diverse platforms, including solid-state devices, ultracold atoms, an…
Nonlinearity-induced Band Gap Transmission in Dispersive and Flat Band Photonic Lattices
Avinash Tetarwal, Shailja Sharma, Sebabrata Mukherjee
Nonlinear interactions in photonic non-dispersive (flat) bands remain largely unexplored, despite their potential to yield exotic phenomena. Here, we demonstrate nonlinearity-induc…
Intensity Correlation Measurement to Simulate Two-body BICs and Probe Nonlinear Discrete Breathers
Trideb Shit, Rishav Hui, Marco Di Liberto +2
We study Hanbury Brown-Twiss spatial intensity correlations in femtosecond laser-fabricated photonic Su-Schrieffer-Heeger lattices using coherent input states with tunable phases.…
