Realizing Nonreciprocal Linear Dichroism and Emission from Simple Media

Kavli Affiliate: Richard D. Robinson | First 5 Authors: Thomas J. Ugras, Thomas J. Ugras, , , | Summary: Reciprocity, the principle that a system response is identical in the forward path compared to the backward path, is a fundamental concept across physics, from electrical circuits and optics to acoustics and heat conduction. Nonreciprocity arises […]

Spin-Polaron Mediated Superconductivity in Doped Chern Antiferromagnets

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Xuepeng Wang, Xuepeng Wang, , , | Summary: The study of interacting topological bands with a tunable bandwidth offers a unique platform to study the interplay of intertwined orders and emergent non-electronic excitations. Here we design a time-reversal symmetric and sign-problem-free electronic model with tunable Chern bands […]

Optically Actuated Transitions in Multimodal, Bistable Micromechanical Oscillators

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Lior Michaeli, Lior Michaeli, , , | Summary: We experimentally demonstrate a new class of optomechanical nonlinearities in weakly damped micromechanical resonators, arising from the interplay between the Duffing nonlinearity, intermodal coupling, and thermal fluctuations. Within the bistable regime of a single Duffing mode driven by […]
