Stability of vortex lines in liquid 3-4He mixtures at zero temperature

At low temperatures and He concentrations below -6.6%, there is experimental evidence about the existence in liquid helium mixtures of stable vortices with He-rich cores. When the system is either supersaturated or submitted to a tensile strength, vortices lose stability becoming metastable and even...
