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…
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…
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…
Theory of Charge Order and Heavy-Electron Formation in the Mixed-Valence Compound KNiSe
James M. Murray, Zlatko Tesanovic
The material KNiSe has recently been shown to possess a number of striking physical properties, many of which are apparently related to the mixed valency of this system, in…
Quantum Criticality for Extended Nodes on a Bethe Lattice in the Large Connectivity Limit
James M. Murray, Adrian Del Maestro, Zlatko Tesanovic
Theoretical description of anisotropic systems, such as layered superconductors and coupled spin chains, is often a challenge due to the different natures of interactions along dif…
