Bose-Einstein condensation in quantum glasses

Giuseppe Carleo, Marco Tarzia, Francesco Zamponi

英文摘要:

The role of geometrical frustration in strongly interacting bosonic systems is studied with a combined numerical and analytical approach. We demonstrate the existence of a novel quantum phase featuring both Bose-Einstein condensation and spin-glass behaviour. The differences between such a phase and the otherwise insulating "Bose glasses" are elucidated.
