Semiclassical dynamics of neutral and charged composite excitations in insulators introduce a generalized quantum geometric dipole and require careful selection among inequivalent composite Berry curvatures based on spatial center definition.
Hubbard operator method captures coupling between localized and itinerant electrons in the topological heavy fermion model, agreeing with DQMC while local approximations like Hubbard-I fail.
Controlled loop expansion in strained MATBG reveals U(1) symmetry suppressing Mott band linewidths at order s² and predicts strain-induced kinks plus a flat trion band, with one-loop QTM spectra compared to experiment.
In the topological heavy fermion model, the Mott semimetal phase hosts well-defined quasiparticles with dispersion and relaxation rate proportional to the interaction strength.
A loop expansion in the topological heavy fermion model yields quasiparticle lifetimes and a Curie-Weiss flavor susceptibility above the ordering temperature despite strong interactions.
Interfering two obliquely propagating surface acoustic waves forms a tunable acoustoelectric superlattice in 2D materials, enabling in-situ control of minibands, flat bands, and nontrivial valley Chern numbers in massive monolayer graphene.
