Non-equilibrium Bose-Einstein Condensation
Vishwanath Shukla, Sergey Nazarenko
We investigate formation of Bose-Einstein condensates under non-equilibrium conditions using numerical simulations of the three-dimensional Gross-Pitaevskii equation. For this, we…
The Vortex-Particle Magnus Effect
Adam Griffin, Sergey Nazarenko, Vishwanath Shukla +1
Experimentalists use particles as tracers in liquid helium. The intrusive effects of particles on the dynamics of vortices remain poorly understood. We implement a study of how bas…
Quantitative estimation of effective viscosity in quantum turbulence
Vishwanath Shukla, Pablo D. Mininni, Giorgio Krstulovic +2
We study freely decaying quantum turbulence by performing high resolution numerical simulations of the Gross-Pitaevskii equation (GPE) in the Taylor-Green geometry. We use resoluti…
Particles and Fields in Superfluids: Insights from the Two-dimensional Gross-Pitaevskii Equation
Vishwanath Shukla, Rahul Pandit, Marc Brachet
We carry out extensive direct numerical simulations (DNSs) to investigate the interaction of active particles and fields in the two-dimensional (2D) Gross-Pitaevskii (GP) superflui…
Sticking Transition in a Minimal Model for the Collisions of Active Particles in Quantum Fluids
Vishwanath Shukla, Marc Brachet, Rahul Pandit
Particles of low velocity, travelling without dissipation in a superfluid, can interact and emit sound when they collide. We propose a minimal model in which the equations of motio…
Superfluid Mutual-friction Coefficients from Vortex Dynamics in the Two-dimensional Galerkin-truncated Gross-Pitaevskii Equation
Vishwanath Shukla, Marc Brachet, Rahul Pandit
We present algorithms for the ab-initio determination of the temperature () dependence of the mutual-friction coefficients and and the normal-fluid density …
