Nonadiabatic Josephson current pumping by microwave irradiation
B. Venitucci, D. Feinberg, R. Mélin +1
Irradiating a Josephson junction with microwaves can operate not only on the amplitude but also on the phase of the Josephson current. This requires breaking time inversion symmetr…
D.C. Josephson transport by quartets and other Andreev resonances in superconducting bijunctions
R. Mélin, D. Feinberg, H. Courtois +8
Bijunctions are three-terminal Josephson junctions where three superconductors are connected by a single weak link made of a metallic region or of quantum dots. Biasing two of the…
Strong disorder renormalization group on fractal lattices: Heisenberg models and magnetoresistive effects in tight binding models
R. Mélin, B. Douçot, F. Iglói
We use a numerical implementation of the strong disorder renormalization group (RG) method to study the low-energy fixed points of random Heisenberg and tight-binding models on dif…
Spin Models on Non-Euclidean Hyperlattices: Griffiths Phases without Extrinsic Disorder
J. C. Angles d'Auriac, R. Melin, P. Chandra +1
We study short-range ferromagnetic models residing on planar manifolds with global negative curvature. We show that the local metric properties of the embedding surface induce drop…
Spin accumulation in the semi classical and quantum regimes
R. Mélin, D. Denaro
We consider spin accumulation at a ferromagnet--normal metal interface in the presence of magnetic scattering in the normal metal. In the classical regime, we discuss the inverse D…
A single chain analysis of doped quasi one dimensional spin 1 compounds: paramagnetic versus spin 1/2 doping
M. Fabrizio, R. Mélin
We present a numerical study of single chain models of doped spin 1 compounds. We use low energy effective one-dimensional models for both the cases of paramagnetic and spin-1/2 do…
