Nonlinear effects in tunnelling escape in N-body quantum systems
arXiv:cond-mat/0409581 · doi:10.1209/epl/i2005-10226-8
Abstract
We consider the problem of tunneling escape of particles from a multiparticle system confined within a potential trap. The process is nonlinear due to the interparticle interaction. Using the hydrodynamic representation for the quantum equations of the multiparticle system we find the tunneling rate and time evolutions of the number of trapped particles for different nonlinearity values.
