Pauli exclusion says no two particles should occupy the same state. Alternatively, it says that exchanging two particles generate a factor of -1. This is a basic fact about a spinor field, as a result of anticommutation relations. However, I hear that in strongly curved space time, QFTs have no interpretation in terms of particles. In this case, do the above two statement of Pauli eclusion fail to make sense, since both of them involve the concept of "particles"?
