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…
Resonance oscillations of non-reciprocal long-range van der Waals forces between atoms in electromagnetic fields
Yury Sherkunov
We study theoretically the van der Waals interaction between two atoms out of equilibrium with isotropic electromagnetic field. We demonstrate that at large interatomic separations…
Optical source of individual pairs of color-conjugated photons
Y. Sherkunov, D. M. Whittaker, V. Falko
We demonstrate that Kerr nonlinearity in optical circuits can lead to both resonant four-wave mixing and photon blockade, which can be used for high-yield generation of high-fideli…
Rabi oscillations of two-photon states in nonlinear optical resonators
Y. Sherkunov, David M. Whittaker, Vladimir Falko
We demonstrate that four-wave mixing processes in high-quality non-linear resonators can lead to Rabi-like oscillations in photon occupation numbers and second-order correlation fu…
