Adiabatic techniques are known to allow for engineering quantum states with high fidelity.
This requirement is currently of large interest, as applications in quantum information require …

Recent experiments on macroscopic quantum tunneling reveal a nonexponential decay of
the number of atoms trapped in a quasibound state behind a potential barrier. Through both …

Tunneling of a quasibound state is a nonsmooth process in the entangled many-body case.
Using time-evolving block decimation, we show that repulsive (attractive) interactions speed …

Two aspects of the transport of a repulsive Bose–Einstein condensate (BEC) in a double-
well trap are inspected: The impact of the interatomic interaction and the analogy with the …

We consider the tunneling properties of a single fermionic impurity immersed in a Bose-
Einstein condensate in a double-well potential. For strong boson-fermion interaction, we …

Dynamics of the repulsive Bose–Einstein condensate (BEC) in a double-well trap is
explored within the 3D time-dependent Gross–Pitaevskii equation. The model avoids …

We propose to control the interatomic interaction in a Bose condensate by using optical
beams forming an atomic trap. It is shown that for a Bose condensate in a double-well …

Для контроля межатомного взаимодействия в бозе-конденсате предложено
использовать оптические пучки, формирующие атомарную ловушку. В модели бозе …

The evolution of mode entanglement is analyzed for a system of two indistinguishable
bosons with two accessible modes. Whereas entanglement remains stationary whenever …

A complete adiabatic transport of Bose-Einstein condensate in a double-well trap is
investigated within the Landau-Zener (LZ), and Gaussian Landau-Zener (GLZ) schemes for …
