Enhancement of specular behavior in atom mirrors with quadrupole-active transitions

open access: yesAlexandria Engineering Journal, 2023
Modern studies have confirmed the possibility of making atomic mirrors using quadrupole-active atomic transition evanescent waves. The reflection process has been shown to be enhanced to approach specular behavior in several ways.

Enhanced quadrupole effects for atoms in surface spiral beams with a thin dielectric waveguide

open access: yesAlexandria Engineering Journal, 2022
Recently, some physical research has recognized the coupling of optical phase singularity light with quadrupole-active atomic transitions. We show that a Laguerre-Gaussian beam, when completely internally reflected at the dielectric/vacuum interface, can

^{1}S_{0}-^{3}P_{2} magnetic quadrupole transition in neutral strontium

open access: yesPhysical Review Research, 2023
We present a detailed investigation of the ultranarrow magnetic-quadrupole ^{1}S_{0}-^{3}P_{2} transition in neutral strontium and show how it can be made accessible for quantum simulation and quantum computation.

Systematic Projected Shell Model Study of Even-Even Dysprosium Isotopes

open access: yesAtom Indonesia, 2022
Back-bending phenomenon is one of the important phenomena usually seen at high spin states of even - even heavy nuclei. As a result, any changes in the behavior of nuclear rotation, such as increase in moment of inertia versus rotational frequency can be

Part-per-billion measurement of the 42S1/2→32D5/2 electric-quadrupole-transition isotope shifts between Ca+42,44,48 and Ca+40 [PDF]

open access: yesPhysical Review A, 2019
We report a precise measurement of the isotope shifts in the $4^2$S$_{1/2} \rightarrow 3^2$D$_{5/2}$ electric quadrupole transition at 729~nm in the $^{40 - 42,44,48}$Ca$^+$.

Quadrupole absorption rate for atoms in circularly-polarized optical vortices

open access: yesResults in Physics, 2021
Twisted light beams, or optical vortices, have been used to drive the circular motion of microscopic particles in optical tweezers and have been shown to generate vortices in quantum gases.
