Theory of weak symmetry breaking of translations in topologically ordered states and its relation to topological superconductivity from an exact lattice charge-flux attachment
Peng Rao, Inti Sodemann
We study topologically ordered states enriched by translational symmetry by employing a recently developed 2D bosonization approach that implements an exact $\mathbb…
Anatomy of Z2 fluxes in anyon Fermi liquids and Bose condensates
Oscar Pozo, Peng Rao, Chuan Chen +1
We study in detail the properties of pi-fluxes embedded in a state with a finite density of anyons that form either a Fermi liquid or a Bose-Einstein condensate. By employing a rec…
Gully quantum Hall ferromagnetism in biased trilayer graphene
Peng Rao, Maksym Serbyn
Multilayer graphene lattices allow for an additional tunability of the band structure by the strong perpendicular electric field. In particular, the emergence of the new multiple D…
Cyclotron resonance inside the Mott gap: a fingerprint of emergent neutral fermions
Peng Rao, Inti Sodemann
A major obstacle to identify exotic quantum phases of matter featuring spin-charge separation above one-dimension is the lack of tailored probes allowing to establish their presenc…
Emergent Dirac gullies and gully-symmetry breaking quantum Hall states in ABA trilayer graphene
Alexander A. Zibrov, Rao Peng, Carlos Kometter +7
We report on quantum capacitance measurements of high quality, graphite- and hexagonal boron nitride encapsulated Bernal stacked trilayer graphene devices. At zero applied magnetic…
