Experimental observation of anomalous topological edge modes in a slowly-driven photonic lattice
Sebabrata Mukherjee, Alexander Spracklen, Manuel Valiente +4
The discovery of the quantised Hall effect, and its subsequent topological explanation, demonstrated the important role topology can play in determining the properties of quantum s…

Observation of pair tunneling and coherent destruction of tunneling in arrays of optical waveguides
Sebabrata Mukherjee, Manuel Valiente, Nathan Goldman +4
We report on the experimental realization of a photonic system that simulates the one-dimensional two-particle Hubbard model. This analogy is realized by means of two-dimensional a…

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…
