Time-domain interferometry of electron weak localization through terahertz nonlinear response
Zi-Long Li, Xiao-Hui Li, Yuan Wan
We study theoretically the nonlinear optical response of disordered electrons in the regime of weak (anti)localization. Our analytical and numerical calculations reveal that, in or…

Photon echo from lensing of fractional excitations in Tomonaga-Luttinger spin liquid
Zi-Long Li, Masaki Oshikawa, Yuan Wan
We study theoretically the nonlinear optical response of Tomonaga-Luttinger spin liquid in the context of terahertz (THz) two-dimensional coherent spectroscopy (2DCS). Using the ga…
