We present and distribute a parallel finite-element toolbox written in the free software
FreeFEM for computing the Bogoliubov-de Gennes (BdG) spectrum of stationary solutions to …

We study the onset of dissipation in an atomic Josephson junction between Fermi
superfluids in the molecular Bose-Einstein condensation limit of strong attraction. Our …

We report an inelastic neutron scattering study on the spin resonance in the bilayer iron-
based superconductor CaKFe 4 As 4. In contrast to its quasi-two-dimensional electron …

Instabilities of vortex-ring-bright coherent structures in harmonically trapped two-component
three-dimensional Bose-Einstein condensates are studied numerically within the coupled …

We use inelastic neutron scattering to study the low-energy spin excitations of the 112-type
iron pnictide Ca 0.82 La 0.18 Fe 0.96 Ni 0.04 As 2 with bulk superconductivity below T c= 22 …

The excited-state structure of atomic nuclei can modify nuclear processes in stellar
environments. In this Letter, we study the influence of nuclear excitations on Urca cooling …

The study of superfluid quantum vortices has long been an important area of research, with
previous work naturally focusing on two-dimensional and three-dimensional systems, where …

The existence of orbital-dependent electronic correlations has been recognized as an
essential ingredient to describe the physics of iron-based superconductors. NaFeAs, a …

In this work we present a systematic study of the three-dimensional extension of the ring
dark soliton, examining its existence, stability, and dynamics in isotropic harmonically …

In the present work, motivated by numerous recent experimental developments we revisit
the dynamics of a single vortex ring in anisotropic harmonic traps. At the theoretical level, we …
