  Spinor bosons offer conceptually simple picture of macroscopic quantum
behavior of topological order-by-disorder: Paramagnetic state of two-component
dipolar bosons in orbitally degenerate zig-zag lattice is unstable against
infinitezimal quantum fluctuations of orbitals towards developing non-local
hidden order. Adjacent to the topological state locally correlated exact ground
state with spontaneously quadrupoled lattice constant is realized for the broad
parameter regime.
