Quantum dynamics of attractive versus repulsive bosonic Josephson junctions: Bose-Hubbard and full-Hamiltonian results
Kaspar Sakmann, Alexej I. Streltsov, Ofir E. Alon +1
The quantum dynamics of one-dimensional bosonic Josephson junctions with attractive and repulsive interparticle interactions is studied using the Bose-Hubbard model and by numerica…
Accurate multi-boson long-time dynamics in triple-well periodic traps
Alexej I. Streltsov, Kaspar Sakmann, Ofir E. Alon +1
To solve the many-boson Schrödinger equation we utilize the Multiconfigurational time-dependent Hartree method for bosons (MCTDHB). To be able to attack larger systems and/or to pr…
Exact quantum dynamics of a bosonic Josephson junction
Kaspar Sakmann, Alexej I. Streltsov, Ofir E. Alon +1
The quantum dynamics of a one-dimensional bosonic Josephson junction is studied by solving the time-dependent many-boson Schrödinger equation numerically exactly. Already for weak…
