Quantum Dynamics of Coupled Bosonic Wells within the Bose-Hubbard Picture
R. Franzosi, V. Penna, R. Zecchina
We relate the quantum dynamics of the Bose-Hubbard model (BHM) to the semiclassical nonlinear equations that describe an array of interacting Bose condensates by implementing a sta…
Self-trapping mechanisms in the dynamics of three coupled Bose-Einstein condensates
Roberto Franzosi, Vittorio Penna
We formulate the dynamics of three coupled Bose-Einstein condensates within a semiclassical scenario based on the standard boson coherent states. We compare such a picture with tha…
String Limit of Vortex Current Algebra
V. Penna, M. Spera
The Poisson structure generating the hamiltonian dynamics of string vortices is reconstructed within the current algebra picture as a limiting case of the standard brackets associa…
Quantum dynamics of two-dimensional vortex pairs with arbitrary total vorticity
V. Penna
Quantum dynamics of a vortex pair is investigated by considering the pair Hamiltonian within various, unequivalent algebraic frameworks. First the vortex pair spectrum is construct…
