Nonlinear Electric and Optical Responses in Quantum Materials

March 3, 2022



Quantum materials with broken symmetry exhibit large nonlinear electric and optical responses associated with geometry and topology of the electronic band structures. In addition to being the powerful probe of symmetries, nonlinear responses give rise to directional, nondissipative, and ultrafast responsive electric current, which potentially enables high-efficiency and low-energy-consumption optoelectronic devices. This topical meeting aims at sharing the recent experimental and theoretical progress in this field and discussing the future research direction.
