Precise control and knowledge over atomic dynamics is central to the advancement of quantum
technology. The different experimental conditions namely, atoms in a vacuum, antirelaxation coated
and buffer gas filled atomic cells provide complementary pl…
The dynamical behaviors of a quasi-2D Bose–Einstein condensate (BEC) with three-body interactions
through a moving obstacle potential are studied numerically. Various vortex structures are
discovered under different strength of three-body interaction…
This paper presents a cavity-assisted coherent feedback scheme to cool a mechanical resonator to the
ground-state in a weak optomechanical coupling setup. Based on the theory of sideband cooling,
resolved sideband regime is a mandatory condition for …
We investigate photoelectron holography in bichromatic linearly polarized fields of commensurate
frequencies rω and sω , with emphasis on the existing symmetries and for which values of the
relative phase between the two driving waves they are kept o…
In the present work, a detailed study has been reported on electron impact elastic scattering from
krypton (Kr) and xenon (Xe) atoms when confined in two different types of C 60 potentials viz (a)
hard annular square well (ASW) and (b) diffused Gauss…
We consider the formation of vibrationally-induced transient electronic coherences driven by conical
intersection (CI)-mediated population transfer between two electronic states. By invoking
fundamental symmetry arguments, we identify several importa…
High-order harmonic generation (HHG) in disordered systems is investigated by numerically solving
the time-dependent Schrödinger equation. We reveal the vital role of Anderson localization in this
situation. It allows us to develop a new and efficien…
We present results of simulations highlighting the performance of a cooling mechanism in a magnetic
trap tailored for excited Rydberg atoms (or molecules) with high magnetic moment. Unlike previous
work, the cooling is achieved through fast stimulate…
We calculate Bardeen–Cooper–Schrieffer (BCS) state of a unitary Fermi gas of atoms interacting with
the finite-ranged Jost-Kohn potential which has been recently shown to account for the resonant
interactions (2019 J. Phys. B: At. Mol. Opt. Phys. 52 …
Spectral line-shape models are an important part of understanding high-energy-density (HED) plasmas.
Models are needed for calculating opacity of materials and can serve as diagnostics for
astrophysical and laboratory plasmas. However, much of the li…
