Stoner transitions beyond mean-field in two-dimensional electronic systems: a diagrammatic Monte Carlo study
Yueh-Chen Lee, Nikolay V. Prokof'ev, Andrey V. Chubukov
The paper investigates ferromagnetic Stoner transitions in two‑dimensional electron systems with one or two valleys beyond the mean‑field ladder approximation, using diagrammatic M…
Non-BCS Pairing by a Singular Dynamical Interaction
Artem G. Abanov, Andrey V. Chubukov
This review examines the theory of superconductivity in systems with {\em singular dynamical} electron-electron interaction and contrasts it with a conventional BCS superconductivi…
Magnetic field induced transition from nodeless to nodal superconductivity in -PdBi
Emmanouil K. Kokkinis, Joseph J. Betouras, Andrey V. Chubukov
Recent tunneling measurements on -PdBi reported a magnetic field induced phase transition from a fully gapped to a nodal superconducting state. We develop a microscopic the…
Avoided Stoner instability at a single ordinary Van Hove point
I. S. Tupitsyn, B. Currie, A. V. Chubukov +3
When the Fermi surface and the Brillouin zone boundary touch at a Van Hove point, mean-field analysis predicts a ferromagnetic (Stoner) instability at finite for any coupl…
Nematic Phase Transitions in Multilayer Graphene Systems
R. David Mayrhofer, Andrey V. Chubukov
Recent experiments on graphene multilayers under displacement field have demonstrated a wide variety of electronically ordered phases, including valley and/or spin polarized phases…
Superconductivity mediated by nematic fluctuations -- the dispersion of collective modes
Kazi Ranjibul Islam, Andrey Chubukov
We analyze the spectrum of collective modes in a superconductor in which pairing is mediated by long-range nematic fluctuations. Previous experimental and theoretical studies have…
