Time-dependent condensation of bosonic potassium

Quantum Gases 2022-11-23 v1 Quantum Physics

Abstract

We calculate the time-dependent formation of Bose--Einstein condensates (BECs) in potassium vapours based on a previously derived exactly solvable nonlinear boson diffusion equation (NBDE). Thermalization following a sudden energy quench from an initial temperature TiT_\mathrm{i} to a final temperature TfT_\mathrm{f} below the critical value and BEC formation are accounted for using closed-form analytical solutions of the NBDE. The time-dependent condensate fraction is compared with available 39^{39}K data for various scattering lengths.
