Condensate Heating by Atomic Losses

TL;DR

This paper investigates how atomic losses lead to heating in Bose-Einstein condensates, with predicted depletion levels varying based on the condensate's geometry and trapping conditions.

Contribution

It provides a theoretical analysis of condensate heating due to atomic losses, quantifying depletion across different geometries and trapping setups.

Findings

Depletion ranges from 1% in uniform 3D condensates to 10% in quasi-1D traps.

Atomic losses significantly contribute to condensate heating.

Theoretical predictions match expected experimental conditions.

Abstract

Atomic Bose-Einstein condensate is heated by atomic losses. Predicted depletion ranges from 1% for a uniform 3D condensate to around 10% for a quasi-1D condensate in a harmonic trap.
