Interplay of superconductivity and spin density wave order in doped graphene
Rahul Nandkishore, Andrey V. Chubukov
We study the interplay between superconductivity and spin density wave order in graphene doped to 3/8 or 5/8 filling (a Van Hove doping). At this doping level, the system is known…
Prediction and description of a chiral pseudogap phase
Rahul Nandkishore
We point out that a system which supports chiral superconductivity should also support a chiral pseudogap phase: a finite temperature phase wherein superconductivity is lost but ti…
Broken translational symmetry in an emergent paramagnetic phase of graphene
Gia-Wei Chern, Rafael M. Fernandes, Rahul Nandkishore +1
We show that the spin-density wave state on the partially filled honeycomb and triangular lattices is preempted by a paramagnetic phase that breaks an emergent Z_4 symmetry of the…
Electron Interactions in Bilayer Graphene: Marginal Fermi Liquid Behaviour and Zero Bias Anomaly
Rahul Nandkishore, Leonid Levitov
We analyze the many-body properties of bilayer graphene (BLG) at charge neutrality, governed by long range interactions between electrons. Perturbation theory in a large number of…
Flavor Symmetry and Competing Orders in Bilayer Graphene
Rahul Nandkishore, Leonid Levitov
We analyze competition between different ordered states in bilayer graphene (BLG). Combining arguments based on SU(4) spin-valley flavor symmetry with a mean field analysis, we ide…
