WebFermi-Dirac statistics, in quantum mechanics, one of two possible ways in which a system of indistinguishable particles can be distributed among a set of energy states: each of the available discrete states can be occupied by only one particle. WebOct 27, 2024 · The first has fermionic charges and bosonic gauge flux loops (FcBl) and is just the ordinary fermionic toric code. The second has fermionic charges and fermionic loops (FcFl), and, as we argue, can only exist at the boundary of a non-trivial 4+1d invertible bosonic phase, stable without any symmetries, i.e. it possesses a gravitational anomaly.

"WebJan 20, 2024 · What's more, the spin-statistics theorem does not say that bosonic fields must commute, and fermionic fields anti-commute. Rather, it says the following: if bosonic fields anti-commute for spacelike separations, then the field must be trivial (and, similarly, so must be fermionic fields if they commute).
