Abstract: The role of geometrical frustration in strongly interacting bosonic systemsis studied with a combined numerical and analytical approach. We demonstratethe existence of a novel quantum phase featuring both Bose-Einsteincondensation and spin-glass behaviour. The differences between such a phase andthe otherwise insulating -Bose glasses- are elucidated.
