✦ Synopsis


In Abelian subalgebras of observables it is shown that the integral representations of states in terms of coherent states result from the indistinguishability of the quanta of the harmonic oscillator under consideration. It is argued that these integral representations contain a quantum de Finetti theorem on Bose-Fock space.

The origin of the transverse relaxation time in optically excited semiconductor quantum wells is investigated based on the vector property of the interband transition matrix elements. The dephasing rate due to carrier-carrier (CC) scattering is found to be equal to half of the common momentum relaxa
