Shedding nano-light on quantum materials

D.N. Basov, Columbia University, https://infrared.cni.columbia.edu

In this talk, I will describe two recent experiments harnessing nano-scale polaritonic waves (“nano-light”) for probing excitonic effects in van der Waals semiconductors[1] and unconventional electronic properties in the nodal metal ZrSiSe [2].
