... Phase-space Distribution? The state of a classical particle is specified by its coordinate and momentum (x,p): phase-space – A state of classical identical particle system can be described by a phase-space distribution f(x,p). Time evolution of f(x,p) obeys the Boltzmann equation. In quantum me ...

introduction to the many-body problem
... i.e., any observable A commutes with any permutation operator. The six permutation operators form a group, and their action on the states given above can be used for constructing irreducible representations of this group. There are two one-dimensional and one two-dimensional irreducible representati ...

Quantum Interference 3 Claude Cohen-Tannoudji Scott Lectures Cambridge, March 9
... This result can be extended to any quantum device which could be introduced for determining the path of the atom. If the device is efficient, i.e. if its two final states are different, the interference fringes disappear. One cannot observe fringes and simultaneously know the path of the atom Illust ...
