Published Sep 15, 2011• 0 citations

Abstract

We show that starting from the Heisenberg equations of motion for Bose annihilation and creation operators and using an appropriate transformation, we can split the Bogoliubov mode into a free particle mode and the amplitude mode. We show this for both the free Bose gas as well as the Bose gas in an optical lattice.

Boltzmann-type collision operators for Bogoliubov excitations of Bose-Einstein condensates: A unified framework

Minh-Binh Tran, Yves Pomeau A

Starting from the Bogoliubov diagonalization for the Hamiltonian of a weakly interacting Bose gas under the presence of a Bose-Einstein condensate, we derive the kinetic equation for the Bogoliubov excitations. Without dropping any of the commutators, we find three collisional processes. One of them describes the 1↔2 interactions between the condensate and the excited atoms. The other two describe the 2↔2 and 1↔3 interactions between the excited atoms themselves.

Solitons of spinor Bose-Einstein condensates in an optical lattice

Yuandong Xie

An improved nonlinear equation different from usual and an improved soliton solution of spinor Bose-Einstein condensates(BES)in an optical lattice are obtained by taking into account a nonlinear term in the equation of motion for probability amplitude of spins carefully.The width, peak and energy of soliton are also found.

Noncondensate atoms in a trapped Bose gas

Juha Javanainen

We formulate Bogoliubov theory for a weakly interacting Bose-Einstein condensate confined to a spherically symmetric harmonic-oscillator potential. The theory is solved numerically by diagonalizing a Hamiltonian that is second order in boson creation and annihilation operators with the aid of a symplectic transformation. At zero temperature, the number of noncondensate atoms is well approximated by a heuristic expression based on Bogoliubov theory for free atoms.

Producing Bose-Einstein Condensates Using Optical Lattices

Maxim Olshanii, David S. Weiss

We relate the entropies of ensembles of atoms in optical lattices to atoms in simple traps. We then determine which ensembles of lattice-bound atoms will adiabatically transform into a Bose condensate. This shows a feasible approach to Bose condensation without evaporative cooling.

Multi-mode description of an interacting Bose-Einstein condensate

Krzysztof Goral, Mariusz Gajda, Kazimierz Rza̧żewski

We study the equilibrium dynamics of a weakly interacting Bose-Einstein condensate trapped in a box. In our approach we use a semiclassical approximation similar to the description of a multi-mode laser. In dynamical equations derived from a full N-body quantum Hamiltonian we substitute all creation (and annihilation) operators (of a particle in a given box state) by appropriate c-number amplitudes. The set of nonlinear equations obtained in this way is solved numerically. We show that on the time scale of a few miliseconds the system exhibits relaxation -- reaches an equilibrium with populations of different eigenstates fluctuating around their mean values.
