The interaction between electrons in graphene under high magnetic fields drives the
formation of a rich set of quantum Hall ferromagnetic (QHFM) phases with broken spin or …

Interacting electrons in flat bands give rise to a variety of quantum phases. One fundamental
aspect of such states is the ordering of the various flavours—such as spin or valley—that the …

Excitons, Coulomb-driven bound states of electrons and holes, are typically composed of
integer charges,. However, in bilayer systems influenced by charge fractionalization,, a more …

Monolayer graphene at charge neutrality in a quantizing magnetic field is a quantum Hall
ferromagnet. Due to the spin and valley (near) degeneracies, there is a plethora of possible …

Magnon, the quanta of spin waves, can serve as an efficient spin information carrier for
memory and logic applications, with the advantages of the Joule-heating free induced low …

Monolayer graphene under a strong magnetic field near charge neutrality manifests the
integer and fractional quantum Hall effects. Since only some of the four spin/valley flavors …

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 …

Recent scanning tunneling microscopy experiments on graphene at charge neutrality under
strong magnetic fields have uncovered a ground state characterized by Kekulé distortion …

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 …

At and near charge neutrality, monolayer graphene in a perpendicular magnetic field is a
quantum Hall ferromagnet. In addition to the highly symmetric Coulomb interaction, residual …
