First order Fermi surface topological (Lifshitz) transition in an interacting two-dimensional Rashba Fermi liquid
Yury Sherkunov, Joseph J. Betouras
We study the Fermi surface topological transition of the pocket-opening type in a two dimensional Fermi liquid with spin-orbit coupling of Rashba type. We find that the interaction…
Novel phases in twisted bilayer graphene at magic angles as a result of van Hove singularities and interactions
Yury Sherkunov, Joseph J. Betouras
The discovery of different phases as a result of correlations, especially in low-dimensional materials, has been always an exciting and fundamental subject of research. Recent expe…
Effects of Lifshitz transitions in ferromagnetic superconductors: the case of URhGe
Yury Sherkunov, Andrey V. Chubukov, Joseph J. Betouras
In ferromagnetic superconductors, like URhGe, superconductivity co-exists with magnetism near zero field, but then re-appears again in a finite field range, where the system also d…
Probing ultra-cold Fermi atoms with a single ion
Y. Sherkunov, B. Muzykantskii, N. d'Ambrumenil +1
We show that the recently proposed ionic microscope set-up [Kollath et.al, PRA, \textbf{76}, 063602 (2007)] could be adapted to measure the \textit {local single-particle energy di…
