Approximating metal–insulator transitions [PDF]
International Journal of Modern Physics B, 2015 We consider quantum wave propagation in one-dimensional quasiperiodic lattices. We propose an iterative construction of quasiperiodic potentials from sequences of potentials with increasing spatial period. At each finite iteration step, the eigenstates reflect the properties of the limiting quasiperiodic potential properties up to a controlled maximum

Metal-insulator transition in transition metal dichalcogenide heterobilayer moiré superlattices [PDF]
Physical Review B, 2021 Moir superlattices formed in two-dimensional semiconductor heterobilayers provide a new realization of Hubbard model physics in which the number of electrons per effective atom can be tuned at will. We report on an exact diagonalization study of the electronic properties of half-filled narrow moir bands in which correlation strengths are varied by ...
