Quantized hydrodynamic model and the dynamic structure factor for a trapped Bose gas.
We quantize the recent hydrodynamic analysis of Stringari for the low-energy collective modes of a trapped Bose gas at T = 0. This is based on the timedependent Gross-Pitaevskii equation, but omits the kinetic energy of the density fluctuations. We diagonalize the hydrodynamic Hamiltonian in terms of the normal modes associated with the amplitude and phase of the inhomogeneous Bose order parame...
متن کاملFinite temperature dynamic structure function of the free Bose gas
A detailed calculation of the finite temperature dynamic structure function of the free Bose gas is presented and discussed. After a short derivation of the expressions describing the exact response S(q,ω;T ) and the impulse approximation (IA) SIA(q,ω; t), their main properties and their evolution with q and T are analyzed. The lowest order energy weighted sum rules of both S(q,ω;T ) and SIA(q,...
متن کاملThe Bose-Hubbard Hamiltonian
One of the exciting prospects of the physics of dilute bose gasses is the realization of optical lattices. The combination of many body physics together with a high degree of tunability makes these systems promising test beds for theoretical techniques and novel devices. In particular given their high degree of quantum coherence they represent the (long term) possibility of a universal quantum ...
متن کاملBose-Hubbard Model
The Bose-Hubbard hamiltonian will be introduced and justified as an effective description of some relevant physical systems (dilute alkali gases in optical lattices, arrays of Josephson junctions). I will also show a mean field theory solution and the resulting phase diagram. Finally, I will describe in detail one of the more important experiments with an optical lattice of Rb atoms. 1. The Bos...
متن کاملA polaritonic two-component Bose–Hubbard model
We demonstrate that polaritons in an array of interacting microcavities with strong atom–photon coupling can form a two-component Bose–Hubbard model in which both polariton species are protected against spontaneous emission as their atomic part is stored in two ground states of the atoms. The parameters of the effective model can be tuned via the driving strength of external lasers and include ...
