Spatial confinement of muonium atoms [PDF]

open access: yesPhysical Review A, 2016
We report the achievement of spatial confinement of muonium atoms (the bound state of a positive muon and an electron). Muonium emitted into vacuum from mesoporous silica reflects between two SiO$_2$ confining surfaces separated by 1 mm. From the data, one can extract that the reflection probability on the confining surfaces kept at 100 K is about 90 ...

Coherent interaction of atoms with a beam of light confined in a light cage

open access: yesLight: Science & Applications, 2021
Light-matter interaction in the hollow-core light cage, at the example of EIT in alkali atoms in this work, presents a novel approach to implement integrated on-chip devices for applications in quantum optics and quantum information.

Emergent s-Wave Interactions between Identical Fermions in Quasi-One-Dimensional Geometries

open access: yesPhysical Review X, 2023
Orbital degrees of freedom play an essential role in metals, semiconductors, and strongly confined electronic systems. Experiments with ultracold atoms have used highly anisotropic confinement to explore low-dimensional physics, but they typically ...

Effective pressures on the outer-, inner-, and shell-confined hydrogenic atoms

open access: yes, 2023
Effective pressures at the boundaries of the outer-, inner-, and shell-confined H atoms are investigated using the numerical differentiation technique in which the system energies are solved by employing the generalized pseudospectral method.

Atoms in boxes: From confined atoms to electron-atom scattering [PDF]

open access: yesThe Journal of Chemical Physics, 2009
We show that both confined atoms and electron-atom scattering can be described by a unified basis set method. The central idea behind this method is to place the atom inside a hard potential sphere, enforced by a standard Slater type basis set multiplied by a cutoff factor.

Transverse Confinement of Photon Position in the Light-Atom Interaction [PDF]

open access: yesPhysical Review Letters, 2021
In light-pulsed atom interferometry, the phase accumulated by atoms depends on the effective wave vector of the absorbed photons. In this work, we proposed a theory model to analyses the effective wave vector of photons in structured light. As for monochromatic optical field, a transverse confinement could lead to diffraction.

Effect of drifts and currents on the validity of a fluid model for the atoms in the plasma edge

open access: yesNuclear Materials and Energy, 2022
The performance of advanced fluid neutral models for the simulation of deuterium atoms in the plasma edge of magnetically confined fusion devices is tested for the first time on cases that include drifts and currents in the plasma model, on a simplified ...

Photoionization of Rydberg atoms in optical lattices

open access: yesNew Journal of Physics, 2021
We develop a formalism for photoionization (PI) and potential energy curves (PECs) of Rydberg atoms in ponderomotive optical lattices and apply it to examples covering several regimes of the optical-lattice depth.

Spin–orbit-coupled Bose–Einstein-condensed atoms confined in annular potentials

open access: yesNew Journal of Physics, 2016
A spin–orbit-coupled Bose–Einstein-condensed cloud of atoms confined in an annular trapping potential shows a variety of phases that we investigate in the present study.
