Abstract
We devise a novel mechanism of isotope separation from a mixture of Bose-Einstein condensate in the presence of interspecies interaction. Fractional revivals of this miscible system are studied inside a ring waveguide for spatially resolving the isotopes of Rb. The characteristic time scale is influenced by the ring radius and the strength of interspecies interaction. We identify the physical parameters for which the autocorrelation function displays the signature of distinguishability. A study of the separability function further suggests favourable time instances for separating the isotopes with greater yields. The precise ranges of ring radius and interspecies interaction strength are revealed. We illustrate condensate densities at proposed time instances, which confirms our results and also validates our method.
Author comments upon resubmission
We are thankful to the reviewer for appreciating the importance and experimental relevance of our work and also for giving important suggestions. We have included the changes in the revised manuscript as per the reviewer's comments, along with a detailed point-wise reply.
List of changes
1. A Table with an appropriate explanation has been included in the revised version of the manuscript for illustrating the values of ring radius, interspecies interaction strength and the corresponding magnetic field values that support maximum S_1 Separability. Also, the experimental values of Feshbach Resonance peak position, width and background scattering length are provided.
2. A subsection about the Isotope Separation in quasi-1D BEC trapped in an infinitesimally thin ring is included in the revised version as per the Reviewer’s comment.
3. One subsection, One table (Tab. 2) and One figure (Fig. 8) are included in the revised manuscript to address the above points.
