Direct observation of chiral order in double layer superfluid — •Arne Ewerbeck, Carl Hippler, Thorge Kock, Robert Büchner, Raphael Eichberger, Matthias Ölschläger, Wen-Min Huang, Ludwig Mathey und Andreas Hemmerich — Institut für Laseryphsik, Hamburg

A double layer chiral superfluid is formed in the second band of a bipartite optical square lattice. In an ballistic expansion process the two layers are superimposed. The Bragg maxima thus observed exhibit interference patterns, which provide direct information on the formation of chiral order and the presence and character of low energy excitations.
