Simple approach for discussing the properties of displaced Fock states

Abstract

With the use of the technique of integration within an ordered product (IWOP) the authors provide a mathematically concise approach for deriving some properties of the displaced Fock states which simplify the previous calculations of Wunsche ibid., vol.3, p.359, 1991. The displaced Fock state representation of the Wigner operator is derived by using the fact that the displaced Fock state is the eigenstate of the Wigner operator.
