Expanding Hermitian operators in a basis of projectors on coherent spin states

Article English OPEN
Weigert, S.;

The expectation values of a Hermitian operator (A) over cap in (2s + 1)(2) specific coherent states of a spin are known to determine the operator unambiguously. As shown here, (almost) any other set of (2s + 1)(2) coherent state projectors also provide a basis for self-... View more
