Abstract

When a ${}^{3}-^{4}$ He mixture is placed inside porous aerogel with an open volume fraction of 0.98, the coexistence region is found to be detached from the superfluid transition line, giving rise to a miscible superfluid mixture at high ${}^{3}{He}$ concentration and low temperature with intriguing properties.
