Quantum particles in noncommutative spacetime: An identity crisis
Quantum particles in noncommutative spacetime: An identity crisis
We argue that the notion of identical particles is no longer well defined in quantum systems governed by noncommutative deformations of spacetime symmetries. Such models are characterized by four-momentum space given by a non-Abelian Lie group. Our analysis is based on the observation that, for states containing more than one …
