Self-similar breakup of a liquid ligament with a solid particle
Sanjay Shukla, Federico Toschi
The breakup of thinning (stretching) liquid ligaments is strongly influenced by localized perturbations arising from impurities or suspended particles. Using numerical simulations…
Vortex Retention Mediated Turbulent Transitions in Self-Gravitating Bosonic and Axionic Condensates
Anirudh Sivakumar, Sanjay Shukla, Rahul Pandit +2
We investigate turbulent spin-down dynamics in self-gravitating Bose-Einstein condensates, comparing purely bosonic and axionic (higher-order interacting) systems. Through simulati…
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…
Neutron-superfluid vortices and proton-superconductor flux tubes: Development of a minimal model for pulsar glitches
Sanjay Shukla, Marc E. Brachet, Rahul Pandit
We develop a theoretical framework that allows us to explore the coupled motion of neutron-superfluid vortices and proton-superconductor flux tubes in a gravitationally collapsed c…
Gravity- and temperature-driven phase transitions in a model for collapsed axionic condensates
Sanjay Shukla, Akhilesh Kumar Verma, Marc E. Brachet +1
We show how to use the cubic-quintic Gross-Pitaevskii-Poisson equation (cq-GPPE) and the cubic-quintic Stochastic Ginzburg-Landau-Poisson equation (cq-SGLPE) to investigate the gra…
