Metastability, collective excitations, and traveling states of one-dimensional spin-orbit-coupled quantum droplets
Harsimranjit Kaur, Ritu, Rajat +2
We study the static and traveling droplet phases of spin-orbit coupled, one-dimensional Bose-Bose mixtures with a Lee-Huang-Yang correction. For the static droplets, employing a va…
Potential-defect-driven collective modes of one-dimensional two-component quantum droplets
Harsimranjit Kaur, Kuldeep Suthar
We examine a one-dimensional binary mixture of ultradilute quantum droplets in the presence of a central potential defect. The properties of the potential strength and the number o…
Structural transition and fragmentation of vortex lattices in rotating tilted dipolar Bose-Einstein condensate
Mamta Ale, Harsimranjit Kaur, Kuldeep Suthar
We investigate the vortex lattices of harmonically confined quasi-two-dimensional tilted rotational dipolar Bose-Einstein condensates. By employing an extended Gross-Pitaevskii equ…
Quasiparticle spectra of mixtures of dipolar and non-dipolar condensates at zero and finite temperatures
Harsimranjit Kaur, Kuldeep Suthar
We examine the low-lying collective quasiparticle modes of a quasi-one-dimensional mixture of Bose-Einstein condensates having dipolar and non-dipolar atomic species. The dipolar a…
Collective modes of two-species Bose-Einstein condensates in a Josephson junction barrier
Harsimranjit Kaur, Kuldeep Suthar
The ultracold atoms are an ideal platform to implement atomtronics and Josephson junctions analogous to superconducting circuits. The collective modes of a Bose gas split by a pote…
