Scaling dynamics of the ultracold Bose gas
Ashton S. Bradley, Jordan Clarke, Tyler W. Neely, and Brian P. Anderson, Phys. Rev. A 106, 053316 – Published 18 November 2022
The large-scale expansion dynamics of quantum gases is a central tool for ultracold gas experiments and poses a significant challenge for theory. In this work we provide an exact reformulation of the Gross-Pitaevskii equation for the ultracold Bose gas in a coordinate frame that adaptively scales with the system size during evolution, enabling simulations of long evolution times during expansion or similar large-scale manipulation.

Conventional wisdom is that quantum effects will tend to disappear as the number of quanta in a system increases, and the evolution of a system will become closer to that described by mean-field classical equations.
