The quantum dynamics of a few bosons in a double well potential is studied using a Bose
Hubbard model. We consider both signs for the on-site interparticle interaction and also …

We present analytical relations for the quantum evolution of the number difference of bosons
between the two sites of a double-well potential, by using perturbative results for small …

The sequential to correlated-tunneling transition of two identical bosons confined in a
symmetrical double well potential is studied using a time-dependent variational formalism …

In this work we investigate the different states of a system of spin-1 bosons in two potential
wells connected by tunneling, with spin-dependent interaction. The model utilizes the well …

Reflection of two strongly interacting bosons with long-rage interaction hopping on a one-
dimensional lattice scattered off by a potential step is theoretically investigated in the …

In this work the two-site Bose–Hubbard model is studied analytically in the limit of weak
coupling u and large number of particles N. In particular, the difference in the occupation …

We study the tunneling of a small ensemble of strongly repulsive bosons in a one-
dimensional (1D) triple-well potential. The usual treatment within the single-band …

In this study we have investigated the quantum tunneling of two repulsive bosons in a triple-
well potential, subject to a high-frequency driving field. By means of the multiple-time-scale …

We consider a theoretical model of a four-mode Bose-Hubbard model consisting of two pairs
of wells coupled via two processes with two different rates. The model is naturally divided …

The extended Bose-Hubbard model for a double-well potential with atom-pair tunneling is
studied. Starting with a classical analysis we determine the existence of three quantum …
