Skin Effect of Nonlinear Optical Responses in Antiferromagnets
Skin Effect of Nonlinear Optical Responses in Antiferromagnets
Nonlinear optics plays important roles in the research of fundamental physics and the applications of highperformance optoelectronic devices. The bulk nonlinear optical responses arise from the uniform light absorption in noncentrosymmetric crystals, and hence are usually considered to be the collective phenomena of all atoms. Here we show, in contrast …
