Dark soliton-like magnetic domain walls in a two-dimensional ferromagnetic superfluid
Xiaoquan Yu, P. B. Blakie
We report a stable magnetic domain wall in a uniform ferromagnetic spin-1 condensate, characterized by the magnetization having a dark soliton profile with nonvanishing superfluid…

Density Resolved Wave Packet Spreading in Disordered Gross-Pitaevskii Lattices
Yagmur Kati, Xiaoquan Yu, Sergej Flach
We perform novel energy and norm density resolved wave packet spreading studies in the disordered Gross-Pitaevskii (GP) lattice to confine energy density fluctuations. We map the l…

Snell's Law for a vortex dipole in a Bose-Einstein condensate
Michael M. Cawte, Xiaoquan Yu, Brian P. Anderson +1
A quantum vortex dipole, comprised of a closely bound pair of vortices of equal strength with opposite circulation, is a spatially localized travelling excitation of a planar super…
