Abstract
We have used torsional oscillators, containing disk-shaped slabs of
superfluid 3He-A, to probe the chiral orbital textures created by cooling into
the superfluid state while continuously rotating. Comparing the observed
flow-driven textural transitions with numerical simulations of possible
textures shows that an oriented monodomain texture with l antiparallel to the
angular velocity Omega_0 is left behind after stopping rotation. The bias
towards a particular chirality, while in the vortex state, is due to the
inequivalence of energies of vortices of opposite circulation. When spun-up
from rest, the critical velocity for vortex nucleation depends on the sense of
rotation, Omega, relative to that of l. A different type of vorticity,
apparently linked to the slab's rim by a domain wall, appears when Omega is
parallel to l.
