Expansion of a one-dimensional Bose gas: the role of interactions and kinetic-energy driving
E. B. Molinero, C. E. Creffield, F. Sols
We study the expansion of a one-dimensional boson gas by suddenly increasing the length of the chain where it resides. We consider three initial ground-state configurations: the Mo…
Tunneling, self-trapping and manipulation of higher modes of a BEC in a double well
J. Gillet, M. A. Garcia-March, Th. Busch +1
We consider an atomic Bose-Einstein condensate trapped in a symmetric one-dimensional double well potential in the four-mode approximation and show that the semiclassical dynamics…
Feshbach-type resonances for two-particle scattering in graphene
C. Gaul, F. Domínguez-Adame, F. Sols +1
Two-particle scattering in graphene is a multichannel problem, where the energies of the identical or opposite-helicity channels lie in disjoint energy segments. Due to the absence…
Expansion of matter waves in static and driven periodic potentials
C. E. Creffield, F. Sols, D. Ciampini +2
We study the non-equilibrium dynamics of cold atoms held in an optical lattice potential. The expansion of an initially confined atom cloud occurs in two phases: an initial quadrat…
Conductances in normal and normal-superconductor structures
F. Sols, J. Sánchez-Cañizares
We study theoretically electronic transport through a normal metal-- superconductor (NS) interface and show that more than one conductance may be defined, depending on the pair of…
Transport in normal-superconductor-normal structures with local conservation of current
J. Sánchez-Cañizares, F. Sols
We study the transport properties of a NSN structure with an insulating barrier at each NS interface. Coherent quasiparticle scattering is assumed and self-consistency is implement…
