Singularity formation in the Gross-Pitaevskii Equation and Collapse in BEC
A. V. Rybin, I. P. Vadeiko, G. G. Varzugin +1
We study a mechanism of collapse of the condensate wave function in the Gross-Pitaevskii theory with attractive interparticle interaction. We reformulate the Gross-Pitaevskii equat…
Temporal and spatial persistence of combustion fronts
J. Merikoski, J. Maunuksela, M. Myllys +2
The spatial and temporal persistence, or first-return distributions are measured for slow combustion fronts in paper. The stationary temporal and (perhaps less convincingly) spatia…
Coherent quantum oscillations in coupled traps with ultracold atoms
N. M. Bogoliubov, J. Timonen, M. B. Zvonarev
The dynamics of two traps with ultracold atoms and connected by Josephson type coupling, is shown to exhibit a transition from dispersive dynamics to localized coherent oscillation…
An algebraic approach to the Tavis-Cummings problem
Ilya P. Vadeiko, Georgii P. Miroshnichenko, Andrei V. Rybin +1
An algebraic method is introduced for an analytical solution of the eigenvalue problem of the Tavis-Cummings (TC) Hamiltonian, based on polynomially deformed su(2), i.e. su_n(2), a…
