Electronic energy spectra and wave functions on the square Fibonacci tiling
Shahar Even-Dar Mandel, Ron Lifshitz
We study the electronic energy spectra and wave functions on the square Fibonacci tiling, using an off-diagonal tight-binding model, in order to determine the exact nature of the t…
Fully three dimensional breather solitons can be created using Feshbach resonance
M. Matuszewski, E. Infeld, B. A. Malomed +1
We investigate the stability properties of breather solitons in a three-dimensional Bose-Einstein Condensate with Feshbach Resonance Management of the scattering length and con ned…
Formation of molecules from a Cs Bose-Einstein condensate
V. A. Yurovsky, A. Ben-Reuven
Conversion of an expanding Bose-Einstein condensate of Cs atoms to a molecular one with an efficiency of more than 30% was observed recently in experiments by M. Mark et al., Europ…
Classical and quantum radiation of perturbed discrete breathers
S. Flach, V. Fleurov, A. V. Gorbach
We show that the linearized phase space flow around a discrete breather solution is not capable of generating persistent energy flow away from the breather even in the case of inst…
