Chemical reactivity of the spherically confined atoms

open access: yes, 2003
Softness, polarizability and mean excitation energy are calculated for several atoms confined in a spherical box, using numerical Hartree-Fock technique with a Dirichlet boundary condition.

Testing quantum correlations in a confined atomic cloud by the scattering of fast atoms [PDF]

open access: yesPhysical Review A, 1999
We suggest measuring one-particle density matrix of a trapped ultracold atomic cloud by scattering fast atoms in a pure momentum state off the cloud. The lowest-order probability of the inelastic process, resulting in a pair of outcoming fast atoms for each incoming one, turns out to be given by a Fourier transform of the density matrix.

Cooperative interactions in dense thermal Rb vapour confined in nm-scale cells [PDF]

open access: yes, 2013
This thesis presents an investigation of the fundamental interaction between light and matter, realised with a rubidium vapour confined in a cell whose thickness (in the propagation direction) is less than the optical wavelength.

Variation of molecular mean free path in confined geometries

open access: yes, 2019
This paper aims to settle disputes in the literature about the spatial variation of the molecular mean free path (MFP) in confined geometries. The MFP of a gas is determined by using both molecular dynamics (MD) and the direct simulation Monte Carlo ...

Laser cooling and loading of Rb into a large period, quasi-electrostatic, optical lattice [PDF]

open access: yes, 2005
This thesis reports on the design and construction of, and results from, an optical-dipole trapping apparatus developed to confine ultracold rubidium atoms in a conservative, large period, optical-dipole trap. An ultra-high vacuum system was designed and

Laser-cooled atoms inside a hollow-core photonic-crystal fiber

open access: yes, 2011
We describe the loading of laser-cooled rubidium atoms into a single-mode hollow-core photonic-crystal fiber. Inside the fiber, the atoms are confined by a far-detuned optical trap and probed by a weak resonant beam. We describe different loading methods

Photon-Assisted Confinement-Induced Resonances for Ultracold Atoms [PDF]

open access: yesPhysical Review Letters, 2014
We solve the two-particle s-wave scattering for an ultracold atom gas confined in a quasi-one-dimensional trapping potential which is periodically modulated. The interaction between the atoms is included in terms of Fermi's pseudopotential. For a modulated isotropic transverse harmonic confinement, the atomic center of mass and relative degrees of ...

Cation hydration by confined water and framework-atoms have crucial role on thermodynamics of clay swelling

open access: yesScientific Reports, 2022
The swelling capacity and stability of clay play a crucial role in various areas ranging from cosmetics to oil extraction; hence change in their swelling behaviour after cation exchange with the surrounding medium is important for their efficient ...
