Anomalous Landau level gaps near magnetic transitions in monolayer WSe
Benjamin A. Foutty, Vladimir Calvera, Zhaoyu Han +7
First-order phase transitions produce abrupt changes to the character of both ground and excited electronic states. Here we conduct electronic compressibility measurements to map t…
Particle-hole asymmetric ferromagnetism and spin textures in the triangular Hubbard-Hofstadter model
Jixun K. Ding, Luhang Yang, Wen O. Wang +8
In a lattice model subject to a perpendicular magnetic field, when the lattice constant is comparable to the magnetic length, one enters the "Hofstadter regime," where continuum La…
Quantum Hall Valley Nematics
S. A. Parameswaran, B. E. Feldman
Two-dimensional electron gases in strong magnetic fields provide a canonical platform for realizing a variety of electronic ordering phenomena. Here we review the physics of one in…
Electron-Hole Asymmetric Integer and Fractional Quantum Hall Effect in Bilayer Graphene
Angela Kou, Benjamin E. Feldman, Andrei J. Levin +4
The nature of fractional quantum Hall (FQH) states is determined by the interplay between the Coulomb interaction and the symmetries of the system. The unique combination of spin,…
Coulomb-driven broken-symmetry states in doubly gated suspended bilayer graphene
R. Thomas Weitz, Monica T. Allen, Benjamin E. Feldman +2
The non-interacting energy spectrum of graphene and its bilayer counterpart consists of multiple degeneracies owing to the inherent spin, valley and layer symmetries. Interactions…
Local Compressibility Measurements of Correlated States in Suspended Bilayer Graphene
Jens Martin, Benjamin E. Feldman, R. Thomas Weitz +2
Bilayer graphene has attracted considerable interest due to the important role played by many-body effects, particularly at low energies. Here we report local compressibility measu…
