Quantized Nonlinear Thouless Pumping
Marius Jürgensen, Sebabrata Mukherjee, Mikael C. Rechtsman
The sharply quantized transport observed in the integer quantum Hall effect can be explained via a simple one-dimensional model with a time-periodic, adiabatically varying potentia…
Observation of a higher-order topological bound state in the continuum
Alexander Cerjan, Marius Jürgensen, Wladimir A. Benalcazar +2
Higher-order topological insulators are a recently discovered class of materials that can possess zero-dimensional localized states regardless of the dimension of the lattice. Here…
Observation of Topological Band Gap Solitons
Sebabrata Mukherjee, Mikael C. Rechtsman
Topological materials exhibit properties dictated by quantised invariants that make them robust against perturbations. This topological protection is a universal wave phenomenon th…
Nonlinear dynamics of Aharonov-Bohm cages
Marco Di Liberto, Sebabrata Mukherjee, Nathan Goldman
The interplay of -flux and lattice geometry can yield full localization of quantum dynamics in lattice systems, a striking interference phenomenon known as Aharonov-Bohm caging.…
Experimental observation of Aharonov-Bohm cages in photonic lattices
Sebabrata Mukherjee, Marco Di Liberto, Patrik Öhberg +2
We report on the experimental realization of a uniform synthetic magnetic flux and the observation of Aharonov-Bohm cages in photonic lattices. Considering a rhombic array of optic…
Modulation-assisted tunneling in laser-fabricated photonic Wannier-Stark ladders
Sebabrata Mukherjee, Alexander Spracklen, Debaditya Choudhury +4
We observe Wannier-Stark localization in curved photonic lattices, realized using arrays of evanescently coupled optical waveguides. By correctly tuning the strength of inter-site…
