Magnifying quantum phase fluctuations with Cooper-pair pairing
W. C. Smith, M. Villiers, A. Marquet +6
Remarkably, complex assemblies of superconducting wires, electrodes, and Josephson junctions are compactly described by a handful of collective phase degrees of freedom that behave…
Simple Floquet-Wannier-Stark-Andreev viewpoint and emergence of low-energy scales in a voltage-biased three-terminal Josephson junction
Régis Mélin, Jean-Guy Caputo, Kang Yang +1
A three-terminal Josephson junction consists of three superconductors coupled coherently to a small nonsuperconducting island, such as a diffusive metal, a single or double quantum…
Large and exact quantum degeneracy in a Skyrmion magnet
B. Doucot, D. L. Kovrizhin, R. Moessner
We identify a large family of ground states of a topological Skyrmion magnet whose classical degeneracy persists to all orders in a semiclassical expansion. This goes along with an…
Triplet FFLO Superconductivity in the doped Kitaev-Heisenberg Honeycomb Model
Tianhan Liu, Cécile Repellin, Benoît Douçot +2
We provide analytical and numerical evidence of a spin-triplet FFLO superconductivity in the itinerant Kitaev-Heisenberg model (anti-ferromagnetic Kitaev coupling and ferromagnetic…
Gate-tunable zero-frequency current cross-correlations of the quartet mode in a voltage-biased three-terminal Josephson junction
Régis Mélin, Moïse Sotto, Denis Feinberg +2
A three-terminal Josephson junction biased at opposite voltages can sustain a phase-sensitive dc-current carrying three-body static phase coherence, known as the "quartet current".…
Anisotropic Quantum Spin Hall Effect, Spin-Orbital Textures and Mott Transition
Tianhan Liu, Benoît Douçot, Karyn Le Hur
We investigate the interplay between topological effects and Mott physics in two dimensions on a graphene-like lattice, via a tight-binding model containing an anisotropic spin-orb…
