Impurity-controlled vortex mobility and pair-breaking in fermionic superfluid rings
BuÄra Tüzemen, Andrea Barresi, Gabriel WlazÅowski +2
Using time-dependent density functional theory, we study how density and size of impurities govern dissipation of persistent currents of fermionic superfluid rings in the BCS regim…
Local Quantum Cooling for Large Fermi Systems with Pairing
J. E. Alba-Arroyo, Daniel PÄcak, Michael McNeil Forbes +1
We present a framework for local quantum cooling that can be efficiently applied to large-scale Fermi systems. The method introduces local Hermitian operators as a cooling potentia…
W-SLDA Toolkit: A simulation platform for ultracold Fermi gases
Gabriel WlazÅowski, Piotr Magierski, Michael McNeil Forbes +1
We present the W-SLDA Toolkit, a general-purpose software package for simulating ultracold Fermi gases within the framework of density functional theory and its time-dependent exte…
Dynamical signature of vortex mass in Fermi superfluids
Andrea Richaud, Matteo Caldara, Massimo Capone +2
Quantum vortices are commonly described as funnel-like objects around which the superfluid swirls, and their motion is typically modeled in terms of massless particles. Here we sho…
Quantum vortex dipole as a probe of the normal component distribution
Andrea Barresi, Piotr Magierski, Gabriel WlazÅowski
We investigate the dynamics of quantum vortex dipoles in a strongly interacting, spin-imbalanced Fermi superfluid at zero temperature. Using fully microscopic time-dependent densit…
Dynamical scheme for computing the mass parameter of a system in a medium
Agata Zdanowicz, Daniel PÄcak, Piotr Magierski +1
We present a new method for extracting a mass parameter using time-dependent density functional theory for an arbitrary physical system, provided the adiabatic limit is achievable.…
