SUMMARY:Berry phases\, wormholes and factorization in AdS/CFT [Remote talk]
DESCRIPTION:Within the AdS/CFT correspondence\, the entanglement properties of the\nCFT are related to wormholes in the dual gravity theory. This gives rise\nto questions about the factorisation properties of the Hilbert spaces on\nboth sides of the correspondence.  We review these issues and show how\nthe Berry phase\, a geometrical phase encoding information about\ntopology\, may be used to reveal similarities between the Hilbert space\nstructure  on both sides of the correspondence. Mathematical concepts\nsuch as coadjoint orbits play an important role. In addition to its\nrelevance for quantum gravity\, this analysis also suggests how to\nexperimentally realise the Berry phase and its relation to entanglement\nin table-top experiments involving photons or electrons. This provides a\nnew example for relations between very different branches of physics\nthat follow from the AdS/CFT correspondence and its generalisations.
