Exotic physics could emerge from interplay between geometry and correlation. In fractional
quantum Hall (FQH) states, novel collective excitations called chiral graviton modes (CGMs) …

We present a bimetric low-energy effective theory of fractional quantum Hall (FQH) states
that describes the topological properties and a gapped collective excitation, known as the …

A fundamental manifestation of the nontrivial correlations of an incompressible fractional
quantum Hall (FQH) state is that an electron added to it disintegrates into more elementary …

At low energy, electrons in doped graphene sheets behave like massless Dirac fermions
with a Fermi velocity, which does not depend on carrier density. Here we show that …

A bstract We consider gapped fractional quantum Hall states on the lowest Landau level
when the Coulomb energy is much smaller than the cyclotron energy. We introduce two …

Fractional quantum Hall liquids exhibit a rich set of excitations, the lowest energy of which
are the magnetorotons with dispersion minima at a finite momentum. We propose a theory of …

The fractional quantum Hall (FQH) effect at the filling factor $\nu= 5/2$ was discovered in
GaAs heterostructures more than 35 years ago. Various topological orders have been …

We show that the Lorentz shear modulus—one of the three elastic moduli of a
homogeneous electron gas in a magnetic field—can be calculated exactly in the limit of high …

Exact diagonalization studies have revealed that the energy spectrum of interacting
electrons in the lowest Landau level splits, nonperturbatively, into bands, which is …

Recent advances in the creation and modulation of graphenelike systems are introducing a
science of “designer Dirac materials”. In its original definition, artificial graphene is a man …
