“The Polar Phase of Superfluid 3He”
Andrew Zimmerman, Northwestern University
The complex order parameter of superfluid 3He allows for a wide array of stable phases with different symmetries. It has long been predicted that a particular phase with the superfluid pairs preferentially aligned in one direction, the polar phase, is stabilized when the superfluid is confined to be quasi one-dimensional. This phase has many interesting properties, most notably the stabilization of half-quantum vortices. I will discuss the efforts of our lab at Northwestern and others to find and explore this new phase of superfluid 3He.
