Metal-insulator transition in transition metal dichalcogenide heterobilayer moiré superlattices
Nicolás Morales-Durán, Pawel Potasz, Allan H. MacDonald
Moiré superlattices formed in two-dimensional semiconductor heterobilayers provide a new realization of Hubbard model physics in which the number of electrons per effective atom ca…
Electron-exciton interactions in the exciton-polaron problem
Dmitry K. Efimkin, Emma K. Laird, Jesper Levinsen +2
Recently, it has been demonstrated that the absorption of moderately doped two-dimensional semiconductors can be described in terms of exciton-polarons. In this scenario, attractiv…
Floquet-engineering topological transitions in a twisted transition metal dichalcogenide homobilayer
Michael Vogl, Martin Rodriguez-Vega, Benedetta Flebus +2
Motivated by the recent experimental realization of twisted transition metal dichalcogenide bilayers, we study a simplified model driven by different forms of monochromatic light.…
Anomalous drag in electron-hole condensates with granulated order
Hong Liu, Allan H. MacDonald, Dmitry K. Efimkin
We explain the strong interlayer drag resistance observed at low temperatures in bilayer electron-hole systems in terms of an interplay between local electron-hole-pair condensatio…
Mirror Symmetry Breaking and Lateral Stacking Shifts in Twisted Trilayer Graphene
Chao Lei, Lukas Linhart, Wei Qin +2
We construct a continuum model of twisted trilayer graphene using {\it ab initio} density-functional-theory calculations, and apply it to address twisted trilayer electronic struct…
Magnetized Topological Insulator Multilayers
Chao Lei, Shu Chen, Allan H. MacDonald
We discuss the magnetic and topological properties of bulk crystals and quasi-two-dimensional thin films formed by stacking intrinsic magnetized topological insulator ( for example…
