Fermionic entanglement and the generation of global symmetry
Jan Zaanen, Leiden Univ. & KITP

Recently signals appeared from various sides (AdS/CFT, condensed matter experiment and -numerics) making me wonder whether a simple general principle might be at work in strongly interacting finite density fermion systems which cannot be handled by conventional technology because of the sign problem. Very different from classical- or bosonic systems this would amount to a generic capacity to generate in the infrared larger global symmetries than are present in the UV, without invoking fine tuning.
