Nanophotonics fundamentals and applications: gauge field for photons and control of heat

Electromagnetic interaction, as one of the most fundamental interactions of the universe, lies at the heart of much of modern science and engineering. Novel mechanisms to control electromagnetic interaction, as evidenced by the recent developments of a wide variety of nanophotonic structures, therefore have broad implications for both fundamental and applied research. In this talk, we present two separate examples of some of our recent works in seeking to create novel electromagnetic interactions, and to exploit these interactions for new applications. We will show that one can achieve an effective gauge field for photons, which leads to a rich set of new non-reciprocal physics effects,  as well as a very promising avenue towards on-chip non-magnetic linear optical isolator. We will also discuss some of our recent works in using nanophotonic structures to control heat flow, with important and cool implications for energy technology.
