Theory of evaporative cooling with energy-dependent elastic scattering cross section and application to metastable helium

open access: yes, 2003
The kinetic theory of evaporative cooling developed by Luiten et al. [Phys. Rev. A 53, 381 (1996)] is extended to include the dependence of the elastic scattering cross section on collision energy.

Collisional properties of cold spin-polarized nitrogen gas: theory, experiment, and prospects as a sympathetic coolant for trapped atoms and molecules [PDF]

open access: yes, 2010
We report a combined experimental and theoretical study of collision-induced dipolar relaxation in a cold spin-polarized gas of atomic nitrogen (N). We use buffer gas cooling to create trapped samples of 14N and 15N atoms with densities 5+/-2 x 10^{12 ...

ABSORBTION DRYING-EVAPORATIVE HEAT USING SYSMEMS FOR COLD PRODUCTION WITH THE USE OF ALTERNATIVE ENERGY SOURCES

open access: yesProblems of the Regional Energetics, 2010
Direct and indirect evaporative coolers with nozzles based on multi channel and multi layer polymeric structures are examined in the paper. Such coolers can be used in both independent and combined variants, as well as a part of solar drying-evaporative ...

Cooling and thermometry of atomic Fermi gases

open access: yes, 2016
We review the status of cooling techniques aimed at achieving the deepest quantum degeneracy for atomic Fermi gases. We first discuss some physical motivations, providing a quantitative assessment of the need for deep quantum degeneracy in relevant ...

Polariton Bose-Einstein condensate at room temperature in a Al(Ga)N nanowire-dielectric microcavity with a spatial potential trap

open access: yes, 2012
A spatial potential trap is formed in a 6.0 {\mu}m Al(Ga)N nanowire by varying the Al composition along its length during epitaxial growth. The polariton emission characteristics of a dielectric microcavity with the single nanowire embedded in-plane has ...

Three-Body Recombination near a Narrow Feshbach Resonance in 6 Li [PDF]

open access: yes, 2018
We experimentally measure and theoretically analyze the three-atom recombination rate, L3, around a narrow s-wave magnetic Feshbach resonance of 6Li−6Li at 543.3 G.
