Polarized Raman spectroscopy study of metallic : a consistent picture of disorder-interrupted unidirectional charge order
Wencan Jin, Siwen Li, Jianpeng Liu +9
We have used rotational anisotropic polarized Raman spectroscopy to study the symmetries, the temperature and the doping dependence of the charge ordered state in metallic $(Sr_{1-…
The pseudo-Landau-level representation of twisted bilayer graphene: band topology and the implications on the correlated insulating phase
Jianpeng Liu, Junwei Liu, Xi Dai
We propose that the electronic structure of twisted bilayer graphene (TBG) can be understood as Dirac fermions coupled with opposite pseudo magnetic fields generated by the moiré p…
Floquet spin and spin-orbital Hamiltonians and doublon-holon generations in periodically driven Mott insulators
Kasra Hejazi, Jianpeng Liu, Leon Balents
We consider Mott insulators driven by periodic coherent laser radiation, using both single orbital and multi-orbital models, noting that the latter is of more interest in solid sta…
Floquet engineering of multi-orbital Mott insulators: applications to orthorhombic titanates
Jianpeng Liu, Kasra Hejazi, Leon Balents
We consider driving multi-orbital Mott insulators using laser radiation. We derive general expressions for periodically driven spin-orbital models using time-dependent perturbation…
