Core-bound waves on a Gross-Pitaevskii vortex

arXiv:2603.05505v1 Announce Type: cross Abstract: We find the dispersion relations of two elusive families of core-bound excitations of the Gross-Pitaevskii (GP) vortex, varicose (axisymmetric) and fluting (quadrupole) waves. For wavelengths of order the healing length, these ...
