TL;DR

This paper investigates the collective excitations in a hybrid atomic-molecular Bose-Einstein condensate, focusing on dipole oscillations and their dependence on system parameters, providing insights for experimental detection.

Contribution

It introduces a variational approach to analyze collective excitations in hybrid condensates and details the behavior of dipole modes with varying detuning.

Findings

Out-of-phase dipole oscillation frequency increases with detuning.

Oscillation frequency is a few times larger than the trap frequency.

Feasible for experimental observation.

Abstract

The collective excitation of hybrid atomic-molecular condensate are studied using variational method. The dipole response of the system is studied in detail. We found that the out-of-phase dipole oscillation frequency increasing slowly with the detuning parameter and is only few times large than the trap frequency making the experimental observation of this mode of vibration feasible.
