Superradiant Quantum Phase transition for Landau Polaritons with Rashba and Zeeman couplings
Guillaume Manzanares, Thierry Champel, Denis Basko +1
We develop a theory of cavity quantum electrodynamics for a two-dimensional electron gas in the presence of Rashba spin-orbit and Zeeman couplings and perpendicular magnetic field,…
Superconducting spin valves based on a single spiral magnetic layer
N. G. Pugach, M. O. Safonchik, V. I. Belotelov +2
A detailed investigation of a superconducting spin-triplet valve is presented. This spin-valve consists of a superconducting film covering a metal with an intrinsic spiral magnetic…
Rashba cavity QED: a route towards the superradiant quantum phase transition
Pierre Nataf, Thierry Champel, Gianni Blatter +1
We develop a theory of cavity quantum electrodynamics for a 2D electron gas in the presence of Rashba spin-orbit coupling and perpendicular static magnetic field, coupled to spatia…
A solvable model of Landau quantization breakdown
Thierry Champel, Serge Florens
Physics of two-dimensional electron gases under perpendicular magnetic field often displays three distinct stages when increasing the field amplitude: a low field regime with class…
Superconducting spin valves controlled by spiral re-orientation in B20-family magnets
N. G. Pugach, M. Safonchik, T. Champel +4
We propose a superconducting spin-triplet valve, which consists of a superconductor and an itinerant magnetic material, with the magnet showing an intrinsic non-collinear order cha…
Topologically-protected entanglement of electron pair cyclotron motions
T. Champel, D. Hernangómez-Pérez, S. Florens
Considering two-dimensional electron gases under a perpendicular magnetic field, we pinpoint a specific kind of long-range bipartite entanglement of the electronic motions. This en…
