Stochastic motion of finite-size immiscible impurities in a dilute quantum fluid at finite temperature
Stochastic motion of finite-size immiscible impurities in a dilute quantum fluid at finite temperature
The dynamics of an active, finite-size, and immiscible impurity in a dilute quantum fluid at finite temperature is characterized by means of numerical simulations of the Fourier truncated Gross-Pitaevskii equation. The impurity is modeled as a localized repulsive potential and described with classical degrees of freedom. It is shown that …
