The ground state of Bose-Einstein condensates with attractive particle interactions is metastable. One of the decay mechanisms of the condensate is a collapse by macroscopic quantum tunneling, which can be described by the bounce trajectory as a solution of the time-dependent Gross-Pitaevskii equation in imaginary time. For condensates with an(More)

The so-called nonspecific factors involved in therapy have received little attention up to the present — namely, that of role induction (preparing the clients for treatment by informing them about the rationale of treatment, the treatment process, and their part in therapy). For this reason, we constructed an induction text for systematic desensitization(More)
