摘要
We propose a new number-difference-phase coherent state analogue in two-mode Pock space by introducing a new operator A = root a(dagger)a - b(dagger)b 1 (a b(dagger)/a(dagger) b)(1/2). The coherent state analogue is the eigenvector of A and possesses non-orthonormal and overcompleteness properties. It is constructed on certain superposition states in the radius direction.
