Diagonal harmonious state representations

  • 63 Accesses

For simple unweighted shift operators a family of complex eigenvalue eigenstates of the shift down operators, called theharmonious states, is constructed. Every density matrix is realized as a weighted sum of projections to the harmonious states; and the weight distributions serve as quasiprobability densities for normal ordered operators.
