Nettet18. nov. 2024 · Download PDF Abstract: We develop a theory for a continuous bandwidth-tuned transition at fixed \textit{fractional} electron filling from a metal with a generic Fermi surface to a `Wigner-Mott' insulator that spontaneously breaks crystalline space-group symmetries. Across the quantum critical point, (i) the entire electronic Fermi surface … Nettet22. mar. 2024 · In particular, the insulating phase at intermediate field is unlikely Anderson insulator or Mott insulator since the field is generally known to enhance the mobility edge [66,67,68] or break Mott insulators [69,70,71]. Thus, it seems natural to speculate that the electrical transport in this monolayer MoS 2 is percolative in nature.
