Linearly Coupled Bose-Einstein Condensates: From Rabi Oscillations and Quasi-Periodic Solutions to Oscillating Domain Walls and Spiral Waves
B. Deconinck, P. G. Kevrekidis, H. E. Nistazakis +1
In this paper, an exact unitary transformation is examined that allows for the construction of solutions of coupled nonlinear Schr{ö}dinger equations with additional linear field c…
Avoiding Infrared Catastrophes in Trapped Bose-Einstein Condensates
P. G. Kevrekidis, G. Theocharis, D. J. Frantzeskakis +1
This paper is concerned with the long wavelength instabilities (infrared catastrophes) occurring in Bose-Einstein condensates (BECs). We examine the modulational instability in ``c…
Modulational Instability in Bose-Einstein Condensates under Feshbach Resonance Management
Z. Rapti, G. Theocharis, P. G. Kevrekidis +1
We investigate the modulational instability of nonlinear Schr{ö}dinger equations with periodic variation of their coefficients. In particular, we focus on the case of the recently…
On the modulational stability of Gross-Pitaevskii type equations in 1+1 dimensions
G. Theocharis, Z. Rapti, P. G. Kevrekidis +2
The modulational stability of the nonlinear Schr{ö}dinger (NLS) equation is examined in the case with a quadratic external potential. This study is motivated by recent experimental…
On the modulational stability of Gross-Pittaevskii type equations in 1+1 dimensions
Z. Rapti, P. G. Kevrekidis, V. V. Konotop
The modulational stability of the nonlinear Schr{ö}dinger (NLS) equation is examined in the cases with linear and quadratic external potential. This study is motivated by recent ex…
