Majorana bands, Berry curvature, and thermal Hall conductivity in the vortex state of a chiral p-wave superconductor
James M. Murray, Oskar Vafek
Majorana quasiparticles localized in vortex cores of a chiral p-wave superconductor hybridize with one another to form bands in a vortex lattice. We begin by solving a fully micros…
Incommensurate spin density wave at a ferromagnetic quantum critical point in a three-dimensional parabolic semimetal
James M. Murray, Oskar Vafek, Leon Balents
We explore the ferromagnetic quantum critical point in a three-dimensional semimetallic system with upward- and downward-dispersing bands touching at the Fermi level. Evaluating th…
Emergence of superconductivity in a doped single-valley quadratic band crossing system of spin-1/2 fermions
Kelly Ann Pawlak, James M. Murray, Oskar Vafek
For two-dimensional single-valley quadratic band crossing systems with weak repulsive electron-electron interactions, we show that upon introducing a chemical potential, particle-h…
Renormalization group study of interaction-driven quantum anomalous Hall and quantum spin Hall phases in quadratic band crossing systems
James M. Murray, Oskar Vafek
It is shown that topological insulating phases driven by interactions can be realized without the need for spin-orbit coupling or large intersite interaction in a two-dimensional s…
Excitonic and superconducting orders from repulsive interaction on the doped honeycomb bilayer
James M. Murray, Oskar Vafek
Using a weak-coupling renormalization group formalism, we study competing ordered phases for repulsively interacting fermions on the bilayer honeycomb lattice away from half-fillin…
Superconductivity on the brink of spin-charge order in doped honeycomb bilayer
Oskar Vafek, James M. Murray, Vladimir Cvetkovic
Using a controlled weak-coupling renormalization group approach, we establish the mechanism of unconventional superconductivity in the vicinity of spin or charge ordered excitonic…
