Fractional Chern insulator edges: crystalline effects and optical measurements
Yan-Qi Wang, Johannes Motruk, Andrey Grankin +1
Edge states of chiral topologically ordered phases are commonly described by chiral Luttinger liquids, effective theories that are exact only in the hydrodynamic limit. Motivated b…
Optical engineering and detection of magnetism in moiré semiconductors
Tsung-Sheng Huang, Andrey Grankin, Yu-Xin Wang +1
We present a general framework for optically inducing, controlling, and probing spin states in moiré systems. In particular, we demonstrate that applying Raman optical drives to mo…
Enhanced Cooper pairing in nano-patterned metals
Masoud Mohammadi-Arzanagh, Andrey Grankin, Victor Galitski +1
Nano-patterning has been shown to be a powerful tool for manipulating the vibrational modes of elastic structures, with applications such as optical-mechanical mode coupling. Inspi…
Negative superfluid density and spatial instabilities in driven superconductors
Andrey Grankin, Victor Galitski, Vadim Oganesyan
We consider excitation of Higgs modes via the modulation of the BCS coupling within the Migdal-Eliashberg-Keldysh theory of time-dependent superconductivity. Despite the presence o…
