چکیده
We investigate the collective oscillations of a Bose condensate in an anisotropic harmonic trap. We analytically calculate the values of the trap deformation for which the normal modes are in resonance. In presence of low-order resonances, the amplitude dependence of frequencies is strongly enhanced. We also study the transition to chaos of the collective modes as a function of the trap anisotropy.

Resonances and Chaos in the Collective Oscillations of a Trapped Bose Condensate
We investigate the collective oscillations of a Bose condensate in an anisotropic harmonic trap.

متن کاملRegular and chaotic dynamics in time-dependent relativistic mean-field theory
Isoscalar and isovector monopole oscillations that correspond to giant resonances in spherical nuclei are described in the framework of time-dependent relativistic mean-field theory. Time-dependent and self-consistent calculations that reproduce experimental data on monopole resonances in Pb show that the motion of the collective coordinate is regular for isoscalar oscillations, and that it bec...

متن کاملTime Dependent Relativistic Mean-field Theory
The relativistic mean-field theory provides a framework in which the nuclear manybody problem is described as a self-consistent system of nucleons and mesons. In the mean-field approximation, the self-consistent time evolution of the nuclear system describes the dynamics of collective motion: double giant resonances, nuclear compressibility from monopole resonances, regular and chaotic dynamics...
متن کاملCoherent atomic oscillations and resonances between coupled Bose-Einstein condensates with time-dependent trapping potential
We study the quantum coherent tunneling between two Bose-Einstein condensates separated through an oscillating trap potential. The cases of slow and rapid varying in the time trap potential are considered. In the case of a slowly varying trap, we study the nonlinear resonances and chaos in the oscillations of the relative atomic population. Using the Melnikov function approach, we find the cond...
