Summary of Research

The broad theme of my research in the Soljacic group is "unconventional" light-matter interactions. In other words: realizing ways for matter to emit light in ways which is conventionally considered too slow to be accessible (i.e., forbidden). Recent advances in nanophotonics point to ways to overcome all of the fundamental limitations of light-matter interactions, even in atomically small systems. Intuitively, this happens by confining light on the scale of atomic orbitals. This allows for realization of a very broad set of emission processes.

My work centers on developing systematically a quantum theory of these unconventional light matter interactions and exploring the consequences of realizing these interactions for photonics, atomic physics, chemical physics, and the countless other fields which use light-matter interactions on a regular basis.
