Topological order-by-disorder in orbitally degenerate dipolar bosons in zig-zag lattice

Quantum Gases 2015-04-28 v1

Abstract

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.
