Transferring vibrational states of trapped atoms via a Rydberg electron
Abhijit Pendse, Sebastian Wüster, Matthew T. Eiles +1
We show theoretically that it is possible to coherently transfer vibrational excitation between trapped neutral atoms over a micrometer apart. To this end we consider three atoms,…
Anisotropic Inflation in Dipolar Bose-Einstein Condensates
Arun Rana, Abhijit Pendse, Sebastian Wüster +1
Early during the era of cosmic inflation, rotational invariance may have been broken, only later emerging as a feature of low-energy physics. This motivates ongoing searches for re…
Capturing spin chain dynamics with periodically projected time-dependent basis
Grace Hsiao-Han Chuang, Abhijit Pendse
Simulating many-body quantum systems poses significant challenges due to the large size of the state space. To address this issue, we propose using an SU(2) coherent state for indi…
Generation and decoherence of soliton spatial superposition states
Abhijit Pendse, Shruti Shirol, Shivakant Tiwari +1
Due to their coherence properties, dilute atomic gas Bose-Einstein condensates seem a versatile platform for controlled creation of mesoscopically entangled states with a large num…
Probing non-locality of interactions in a Bose-Einstein Condensate using solitons
Abhijit Pendse, A. Bhattacharyay
We consider a Bose-Einstein Condensate(BEC) with non-local inter-particle interactions. The local Gross-Pitaevskii(GP) equation is valid for the gas parameter $ν=: a^{3} n_{0} << 1…
Effect of finite range interactions on roton mode softening in a multi-component BEC
Abhijit Pendse
We consider the Gross-Pitaevskii(GP) model of a Bose-Einstein Condensate(BEC) for single-component and multi-component BEC. The pseudopotential for s-wave scattering between atoms…
Effect of non-local interactions on the vortex solution in Bose-Einstein Condensates
Abhijit Pendse, A. Bhattacharyay
We consider the Gross-Pitaevskii (GP) model of a Bose-Einstein Condensate (BEC) to study a single vortex line in the presence of non-local repulsive s-wave scattering. We show that…
Long-range s-wave interactions in Bose-Einstein Condensates: An exact correspondence between truncated free energy and dynamics
Abhijit Pendse
We consider the Gross-Pitaevskii(GP) model of a Bose-Einstein Condensate(BEC) with non-local s-wave interactions. The non-locality is represented by corrections to the local GP equ…
Long range interaction induced density modulated state in a Bose-Einstein condensate
Abhijit Pendse, A. Bhattacharyay
We consider a Gross-Pitaevskii model of BEC with non-local s-wave scattering to study the density modulated state in 1D. We resort to a perturbative Taylor series expansion for the…
Amplitude modulated phase in a Bose-Einstein condensate: the role of non-local interactions
Abhijit Pendse, A. Bhattacharyay
We consider a Gross-Pitaevskii model of BEC with non-local interactions of range of the order of the s-wave scattering length. With this model, we study the density modulated phase…
