Query: Spontaneous symmetry breaking in rotating condensates of ultracold atoms   We describe an equilibrium state of a rotating trapped atomic condensate,
which is characterized by a non-zero internal circulation and spontaneous
breaking of the rotational O(2) symmetry with all three major semiaxes of the
condensate having different values. The macroscopic rotation of the condensate
is supported by a mesh of quantized vortices, whose number density is a
function of internal circulation. The oscillation modes of this state are
computed and the Goldstone mode associated with the loss of the symmetry is
identified. The possible avenues for experimental identification this state are
discussed.
