In the last decade, graphene has become an exciting platform for electron optical
experiments, in some aspects superior to conventional two-dimensional electron gases …

When electrons populate a flat band their kinetic energy becomes negligible, forcing them to
organize in exotic many-body states to minimize their Coulomb energy,,,–. The zeroth …

Undoped graphene is a gapless semiconductor; however, when placed under a high
perpendicular magnetic field and cooled to low temperature, it develops an insulating state …

The quantum Hall (QH) effect, a topologically non-trivial quantum phase, expanded the
concept of topological order in physics bringing into focus the intimate relation between the …

Quantum Hall (QH) edge channels propagating along the periphery of two-dimensional (2D)
electron gases under perpendicular magnetic field are a major paradigm in physics …

We investigate interaction-driven integer quantum Hall states realized in Landau levels of
monolayer graphene when two out of its four nearly degenerate spin-valley flavors are filled …

We investigate spin-and valley-symmetry-broken fractional quantum Hall phases within a
formalism that naturally extends the paradigm of quantum Hall ferromagnetism from integer …

As a consequence of the approximate spin-valley symmetry in graphene, the ground state of
electrons in graphene at charge neutrality is a particular SU (4) quantum Hall ferromagnet to …

In graphene, the approximate SU (4) symmetry associated with the spin and valley degrees
of freedom in the quantum Hall (QH) regime is reflected in the fourfold degeneracy of …

Undoped graphene in a strong, tilted magnetic field exhibits a radical change in conduction
upon changing the tilt angle, which can be attributed to a quantum phase transition from a …
