Minimum Dielectric-Resonator Mode Volumes
Qingqing Zhao, Lang Zhang, Owen D. Miller
We show that global lower bounds to the mode volume of a dielectric resonator can be computed via Lagrangian duality. State-of-the-art designs rely on sharp tips, but such structur…

Optimal materials for maximum near-field radiative heat transfer
Lang Zhang, Owen D. Miller
We consider the space of all causal bulk materials, 2D materials, and metamaterials for maximum near-field radiative heat transfer (RHT). Causality constrains the bandwidth over wh…

Maximal single-frequency electromagnetic response
Zeyu Kuang, Lang Zhang, Owen D. Miller
Modern nanophotonic and meta-optical devices utilize a tremendous number of structural degrees of freedom to enhance light--matter interactions. A fundamental question is how large…
