STATISTICAL FIELD THEORY
... many-body wave function |Ψ(t), however, has to be symmetric or antisymmetric under permutations of bosonic or fermionic particles, respectively. Therefore it is more convenient to use a properly (anti)symmetrized version of the above basis, i.e., the states |{Nn,α } with the occupation numbers Nn, ...

CHARACTERIZATION OF THE SEQUENTIAL PRODUCT ON
... us assume that A and B commute. Physically, we are therefore assuming that measurements of A do not affect B and vice-versa. Therefore, the sequential product should be symmetric: measuring A first and B second should be the same as measuring B first and A second. Even more concretely, since A and B ...
