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…
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…
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.…
Mutual friction and vortex Hall angle in a strongly interacting Fermi superfluid
Nicola Grani, Diego Hernández-Rajkov, Cyprien Daix +8
The motion of a quantized vortex is intimately connected with its microscopic structure and the elementary excitations of the surrounding fluid. In this work, we investigate the tw…
Stability of persistent currents in superfluid fermionic rings
Klejdja Xhani, Andrea Barresi, Marek Tylutki +2
We investigate the stability of persistent currents in superfluid fermionic gases confined to a ring geometry. Our study, conducted at zero temperature using time-dependent density…
