Self-gravitating Superfluids: The Gross-Pitaevskii-Poisson Framework
Sanjay Shukla, Marc E. Brachet, Rahul Pandit
We provide an overview of the Gross-Pitaevskii-Poisson equation (GPPE) that is used to model self-gravitating superfluid systems, which include gravitationally collapsed boson and…
Dynamics of Superfluid-Superconducting Magnetars: Magnetic Field Evolution and Gravitational Waves
Sanjay Shukla, Rahul Pandit
Magnetars, highly magnetized neutron stars, host superconducting and superfluid phases. We develop a minimal model that captures the interplay between neutron superfluidity, proton…
Turbulence and large-scale structures in self-gravitating superfluids
Sanjay Shukla
We study turbulence in self-gravitating superfluids by performing direct numerical simulations of the 3D Gross-Pitaevskii-Poisson (GPP) equation, which is also a model for dark mat…
Capture and release of quantum vortices using mechanical devices in low-temperature superfluids
Sanjay Shukla, Giorgio Krstulovic, Rahul Pandit
We show that the Gross-Pitaevskii equation coupled with the wave equation for a wire (GP-W) provides a natural theoretical framework for understanding recent experiments employing…
