Active topological photonics
Yasutomo Ota, Kenta Takata, Tomoki Ozawa +6
Topological photonics has emerged as a novel route to engineer the flow of light. Topologically-protected photonic edge modes, which are supported at the perimeters of topologicall…
Topological quantum matter in synthetic dimensions
Tomoki Ozawa, Hannah M. Price
In the field of quantum simulation of condensed matter phenomena by artificially engineering the Hamiltonian of an atomic, molecular or optical system, the concept of `synthetic di…
Synthetic dimensions and topological chiral currents in mesoscopic rings
Hannah M. Price, Tomoki Ozawa, Henning Schomerus
The recently-introduced concept of "synthetic dimensions" allows for the realization of higher-dimensional topological phenomena in lower-dimensional systems. In this work we study…
Probing localization and quantum geometry by spectroscopy
Tomoki Ozawa, Nathan Goldman
The spatial localization of quantum states plays a central role in condensed-matter phenomena, ranging from many-body localization to topological matter. Building on the dissipatio…
