We introduce the notion of nonreciprocal superconductors where inversion and time-
reversal symmetries are broken, giving rise to an asymmetric energy dispersion. We …

We investigate a mechanism to produce superconductivity by strong purely repulsive
interactions for flat dispersion ɛ∼ k 4 without using the pairing instability in a Fermi liquid …

We performed a random phase approximation (RPA) calculation for a spin-valley polarized
model of the rhombohedral tetra-layer graphene to study the possibility of chiral …

Coulomb repulsion can, counterintuitively, mediate Cooper pairing via the Kohn-Luttinger
mechanism. However, it is commonly believed that observability of the effect requires …

Motivated by the recent discovery of superconductivity in tetralayer graphene, we investigate
the pairing mechanism arising from density-density interactions within the random phase …

We propose a minimal model starting from a parent Chern band with quartic dispersion that
can describe the spin-valley polarized electrons in rhombohedral tetra-layer graphene. The …

Motivated by recent experiments showing evidence for chiral superconductivity in an
anomalous Hall phase of tetralayer graphene, we study the relation between the normal …
