Magnetization distribution and orbital moment in the non-Superconducting Chalcogenide Compound K0.8Fe1.6Se2 [PDF]
, 2013 We have used polarized and unpolarized neutron diffraction to determine the spatial distribution of the magnetization density induced by a magnetic field of 9 T in the tetragonal phase of K0.8Fe1.6Se2.

Photoionization of Rydberg atoms in optical lattices
New 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.

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

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

A Storage Ring for Neutral Atoms [PDF]
, 2001 We have demonstrated a storage ring for ultra-cold neutral atoms. Atoms with mean velocities of 1 m/s corresponding to kinetic energies of ~100 neV are confined to a 2 cm diameter ring by magnetic forces produced by two current-carrying wires. Up to 10^6

Improving efficiency of sympathetic cooling in atom-ion and atom-atom confined collisions [PDF]
Physical Review A, 2021 We propose a new way for sympathetic cooling of ions in an electromagnetic Paul trap: it implies the use for this purpose of cold buffer atoms in the region of atom-ion confinement-induced resonance (CIR). The problem is that the unavoidable micromotion of the ion and the long-range nature of its interaction with the environment of colder atoms in a ...

Ordering in one-dimensional few-fermion clusters with repulsive interactions
New Journal of Physics, 2016 By using a diffusion Monte Carlo (DMC) technique, we studied the behaviour of a mixture of spin-up and spin-down cold fermionic atoms confined in one-dimensional harmonic potentials.

Exact one-particle density matrix for SU(N) fermionic matter-waves in the strong repulsive limit
SciPost Physics, 2023 We consider a gas of repulsive $N$-component fermions confined in a ring-shaped potential, subjected to an effective magnetic field. For large repulsion strengths, we work out a Bethe ansatz scheme to compute the two-point correlation matrix and then ...
