Floquet topological system based on frequency-modulated classical coupled harmonic oscillators
Grazia Salerno, Tomoki Ozawa, Hannah M. Price +1
We theoretically propose how to observe topological effects in a generic classical system of coupled harmonic oscillators, such as classical pendula or lumped-element electric circ…
Synthetic dimensions in integrated photonics: From optical isolation to 4D quantum Hall physics
Tomoki Ozawa, Hannah M. Price, Nathan Goldman +2
Recent technological advances in integrated photonics have spurred on the study of topological phenomena in engineered bosonic systems. Indeed, the controllability of silicon ring-…
Momentum-space Landau levels in driven-dissipative cavity arrays
Andrei C. Berceanu, Hannah M. Price, Tomoki Ozawa +1
We theoretically study the driven-dissipative Harper-Hofstadter model on a 2D square lattice in the presence of a weak harmonic trap. Without pumping and loss, the eigenstates of t…
Four-Dimensional Quantum Hall Effect with Ultracold Atoms
Hannah M. Price, Oded Zilberberg, Tomoki Ozawa +2
We propose a realistic scheme to detect the 4D quantum Hall effect using ultracold atoms. Based on contemporary technology, motion along a synthetic fourth dimension can be accompl…
Edge states in polariton honeycomb lattices
M. Milicevic, T. Ozawa, P. Andreakou +8
The experimental study of edge states in atomically-thin layered materials remains a challenge due to the difficult control of the geometry of the sample terminations, the stabilit…
How to directly observe Landau levels in driven-dissipative strained honeycomb lattices
Grazia Salerno, Tomoki Ozawa, Hannah M. Price +1
We study the driven-dissipative steady-state of a coherently-driven Bose field in a honeycomb lattice geometry. In the presence of a suitable spatial modulation of the hopping ampl…
