Boson thermodynamics in the gravity field
Loris Ferrari, Fabrizio Pavan
A uniform force like the weight has been shown to forbid Bose-Einstein condensation (BEC), due to the discreteness of the Airy spectrum, resulting from the weight. We show that BEC…
Bogoliubov theory of interacting bosons: new insights from an old problem
Loris Ferrari
In a gas of interacting bosons, the Hamiltonian , obtained by dropping all the interaction terms between free bosons with moment , is diagona…
Exact diagonalization of the truncated Bogoliubov Hamiltonian
Loris Ferrari
The present short note is simply intended to communicate that I have analytically diagonalized the Bogoliubov truncated Hamiltonian ~\cite{Bogo1,Bogo2}, in an interacting boso…
Exact canonic eigenstates of the truncated Bogoliubov Hamiltonian in an interacting bosons gas
Loris Ferrari
In a gas of weakly interacting bosons \cite{Bogo1, Bogo2}, a truncated canonic Hamiltonian follows from dropping all the interaction terms between free bosons…
Bound states and expansion dynamics of interacting bosons on a one-dimensional lattice
Cristian Degli Esposti Boschi, Elisa Ercolessi, Loris Ferrari +3
The expansion dynamics of bosonic gases in optical lattices has recently been the focus of increasing attention, both experimental and theoretical. We consider, by means of numeric…
