 SIAM Journal of Applied Dynamical Systems
, 2005
"... We consider the GrossPitaevskii (GP) equation in the presence of periodic and quasiperiodic superlattices to study cigarshaped BoseEinstein condensates (BECs) in such lattice potentials. We examine both stable and unstable solitary wave solutions and illustrate their dynamical stability numerical ..."

BoseEinstein condensates in spatially periodic potentials
 Phys. Rev. A
, 1998
"... Introduction BoseEinstein condensation in trapped dilute gases 1, 2, 3 was observed only recently. Nevertheless, the experimental developments in this field have advanced rapidly, and the properties of condensates in different circumstances have become a matter of practical interest. In this wor ..."

. In this work we study the influence of a spatially periodic external potential on the properties of a BoseEinstein condensate, as reported elsewhere in more detail 4 . Such a periodic potential may be induced by a faroff resonant laser field, and with present trapped condensates it is possible to have a
Quasiperiodic Dynamics in BoseEinstein Condensates in Periodic Lattices and Superlattices
, 2008
"... Authors ’ note: We rephrased the abstract. We employ KAM theory to rigorously investigate quasiperiodic dynamics in cigarshaped BoseEinstein condensates (BEC) in periodic lattices and superlattices. Toward this end, we apply a coherent structure ansatz to the GrossPitaevskii equation to obtain a ..."

Resonant and nonresonant modulated amplitude waves for binary Bose–Einstein condensates in optical lattices
, 2004
"... We consider a system of two Gross–Pitaevskii (GP) equations, in the presence of an opticallattice (OL) potential, coupled by both nonlinear and linear terms. This system describes a Bose–Einstein condensate (BEC) composed of two different spin states of the same atomic species, which interact linea ..."

"... We consider a binary mixture of two overlapping BoseEinstein condensates in two different hyperfine states of 87 Rb with nearly identical magnetic moments. Such a system has been simply realized through application of radiofrequency and microwave radiation which drives a twophoton transition betwe ..."

FESHBACH SHAPE RESONANCES IN MULTIBAND HIGH TC SUPERCONDUCTORS
"... We describe particular nanoarchitectures (superlattices of superconducting wires and layers) where a mechanism to evade temperature decoherence effects in a quantum condensate is switched on by tuning the charge density. The superlattice structure determines the subbands and the corresponding Bloch ..."

"... In this thesis, two sets of experimental studies in bosonic and fermionic gases are described. In the first part of the thesis, itinerant ferromagnetism was studied in a strongly interacting Fermi gas of ultracold atoms. The observation of nonmonotonic behavior of lifetime, kinetic energy, and size ..."

In the second part of the thesis, the coherence properties of a BoseEinstein condensate (BEC) was studied in a radio frequency induced doublewell potential implemented on a microfabricated atom chip. We observed phase coherence between the separated condensates for times up to 200 ms after
