Cold Atoms Beyond Atomic Physics [PDF]

Brazilian Journal of Physics, 2020
In the last 25 years, much progress has been made producing and controlling Bose-Einstein condensates (BECs) and degenerate Fermi gases. The advances in trapping, cooling and tuning the interparticle interactions in these cold atom systems lead to an unprecedented amount of control that one can exert over them.

High resolution spectroscopy of the “ΣN cusp” by using the d(K−, π−) reaction [PDF]

EPJ Web of Conferences, 2022
We present a new proposal, J-PARC E90, to measure a missing-mass spectrum near the ΣN threshold for the d(K−, π−) reactions at 1.4 GeV/c. While many previous experiments support apparent enhancement near the ΣN thresh-old, the dynamical origin of this so-

Improving Efficiency of Sympathetic Cooling in Atom-Ion and Atom-Atom Confined Collisions [PDF]

Phys. Rev. A 103, 053109 (2021), 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 ...

Thermalization of a Trapped Single Atom with an Atomic Thermal Bath [PDF]

Applied Sciences. 2021; 11(5):2258, 2021
We studied a single atom trapped in an optical tweezer interacting with a thermal bath of ultracold atoms of a different species. Because of the collisions between the trapped atom and the bath atoms, the trapped atom undergoes changes in its vibrational states occupation to reach thermal equilibrium with the bath.

Atom-surface physics: A review [PDF]

AVS Quantum Science, 2021
An atom in front of a surface is one of the simplest and fundamental problem in physics. Yet, it allows testing quantum electrodynamics, while providing potential platforms and interfaces for quantum technologies. Despite its simplicity, combined with strong scientific and technological interests, atom-surface physics, at its fundamental level, remains

State-selective Charge Exchange in 19.5–100 keV amu−1 O6+ Collision with He and H2

The Astrophysical Journal Supplement Series, 2023
The cross sections of state-selective charge exchange (CX) between highly charged ions and neutrals are important for modeling extreme ultraviolet and soft X-ray emissions in many astrophysical objects with hot plasma impacting cold media.
