Title: Electron-electron Interaction Physics in Two-Dimensional Materials

 

Abstract:

  Two-dimensional (2D) materials are interesting in part because their electron density can be varied in situ by transferring charge from nearby metallic layers, and because 2D materials can be stacked in a wide variety of configurations to achieve quite different physics properties.  My talk will explain several theoretically imagined examples of electron-electron interaction physics in 2D materials, some of which have already been realized experimentally.  I will briefly discuss spatially-indirect exciton condensate superfluids in transition metal dichalcogenides, broken chiral symmetry and anomalous quantum Hall states in multi-layer graphene, and superconductivity in various materials.
