Classical Hydrodynamics and Coarse-Grained Quantum Turbulence
POSTER
Abstract
Pulsar glitches are not fully understood, but likely are related to instabilities in a coarse-grained hydrodynamic description of superfluids present in neutron stars. In this work, I will address how classical hydrodynamic turbulence emerges by coarse-graining microscopic simulations of quantum turbulence. We investigate both bosonic superfluids, described by the Gross-Pitaevskii Equation (GPE), and fermionic superfluids, modeled by the Superfluid Local Density Approximation (SLDA).
