Ultrahigh-Q chiral resonances empowered by multi-head attention deep learning
Cong Zhang, Jiaju Wu, Huazheng Wu +9
High quality (Q) factor optical chiral resonators are indispensable for many chiral photonic devices. Designing ultrahigh Q-factors in chiral metasurfaces traditionally relies on e…

Correlated quantum shift vector of particle-hole excitations
Xu Yang, Ajit Srivastava, Justin C. W. Song
Excitons are a prime example of how electron interactions affect optical response and excitation. We demonstrate that, beyond its spectra, the bound nature of an exciton's electron…

Nonlinear thermoelectric effects as a means to probe quantum geometry
Xu Yang, Brian Skinner
The quantum geometric tensor, which has the quantum metric and Berry curvature as its real and imaginary parts, plays a key role in the transport properties of condensed matter sys…
