Electromagnetic asymmetry and optical magnetism in symmetry-broken plasmonic nanocavities

In this talk, I will discuss three "dark" aspects of symmetry-broken plasmonic nanocavities, namely 1) light-induced electromagnetic asymmetry [Nature Communications 2021, 12, 4326], 2) plasmon-induced optical magnetism [Laser & Photonics Reviews 2020, 14(9), 200068] and 3) optical magnetism driven multiphoton luminescence [Nano Letters 2021, 21(6), 2453-2406].
