Nucleation and kinematics of vortices in stirred Bose Einstein condensates
Jonas Rønning, Luiza Angheluta
We apply the Halperin-Mazenco formalism within the Gross-Pitaevskii theory to characterise the kinematics and nucleation of quantum vortices in a two-dimensional stirred Bose Einst…
Symmetry-restoring crossover from defect-free to defect-laden turbulence in polar active matter
Benjamin H. Andersen, Julian Renaud, Jonas Rønning +2
Coherent flows of self-propelled particles are characterized by vortices and jets that sustain chaotic flows, referred to as active turbulence. Here, we reveal a crossover between…
Defect self-propulsion in active nematic films with spatially-varying activity
Jonas Rønning, M. Cristina Marchetti, Luiza Angheluta
We study the dynamics of topological defects in active nematic films with spatially-varying activity and consider two setups: i) a constant activity gradient, and ii) a sharp jump…
Trapping of active Brownian and run-and-tumble particles: a first-passage time approach
Emily Qing Zang Moen, Kristian Stølevik Olsen, Jonas Rønning +1
We use a first-passage time approach to study the statistics of the trapping times induced by persistent motion of active particles colliding with flat boundaries. The angular firs…
