Confinement vs Deconfinement of Cooper Pairs in One-Dimensional Spin-3/2 Fermionic Cold Atoms
S. Capponi, G. Roux, P. Azaria +2
The phase diagram of spin-3/2 fermionic cold atoms trapped in a one-dimensional optical lattice is investigated at quarter filling (one atom per site) by means of large-scale numer…
Nature of the deconfining phase transition in the 2+1-dimensional SU(N) Georgi-Glashow model
Philippe Lecheminant
The nature of the deconfining phase transition in the 2+1-dimensional SU(N) Georgi-Glashow model is investigated. Within the dimensional-reduction hypothesis, the properties of the…
Electromagnetically induced switching of ferroelectric thin films
J. -G. Caputo, E. V. Kazantseva, A. I. Maimistov
We analyze the interaction of an electromagnetic spike (one cycle) with a thin layer of ferroelectric medium with two equilibrium states. The model is the set of Maxwell equations…
Vortex polarity switching by a spin--polarized current
Jean-Guy Caputo, Yuri Gaididei, Franz G. Mertens +1
The spin-transfer effect is investigated for the vortex state of a magnetic nanodot. A spin current is shown to act similarly to an effective magnetic field perpendicular to the na…
