Unconventional antiferromagnetic correlations of the doped Haldane gap system YBaNiZnO
V. Villar, R. Mélin, C. Paulsen +3
We make a new proposal to describe the very low temperature susceptibility of the doped Haldane gap compound YBaNiZnO. We propose a new mean field model relevan…

Transport theory of multiterminal hybrid structures
R. Mélin, D. Feinberg
We derive a microscopic transport theory of multiterminal hybrid structures in which a superconductor is connected to several spin-polarized electrodes. We discuss the non-perturba…

Glauber Dynamics and Ageing
R. Mélin, P. Butaud
The Glauber dynamics of various models (REM-like trap models, Brownian motion, BM model, Ising chain and SK model) is analyzed in relation with the existence of ageing. From a fini…
