Abstract

Given the right set of circumstances, ultracold quantum gases are able to change character and condense into a liquid state of quantum droplets. The size distribution of the droplets is determined dynamically in the condensation process. A semi-quantitative argument is presented which suggests that, at zero temperature, a multiple droplet system has is a preferred scale ∝ v^-1/3, where v is the rate of change of parameters at the time of droplet formation. Numerical simulations of two dimensional systems strongly support a power law v^-d, with an exponent d∈(0.327,0.375).
