Alternative derivation of the Pegg-Barnett phase operator.
نویسندگان
چکیده
An alternative derivation of the Pegg-Barnett phase operator is presented. This approach is based on the properties of the representation in quantum mechanics of a nonlinear nonbijective canonical transformation. It does not use as its starting point either a finite-dimensional space or the definition of phase states. The features of this formalism are analyzed in terms of this transformation.

Intermediate coherent-phase(PB) states of radiation fields and their nonclassical properties
Intermediate states interpolating coherent states and Pegg-Barnett phase states are investigated using the ladder operator approach. These states reduce to coherent and Pegg-Barnett phase states in two different limits. Statistical and squeezing properties are studied in detail.

متن کاملOn the Quantum Phase Operator for Coherent States
In papers by Lynch [Phys. Rev. A41, 2841 (1990)] and Gerry and Urbanski [Phys. Rev. A42, 662 (1990)] it has been argued that the phase-fluctuation laser experiments of Gerhardt, Büchler and Lifkin [Phys. Lett. 49A, 119 (1974)] are in good agreement with the variance of the Pegg-Barnett phase operator for a coherent state, even for a small number of photons. We argue that this is not conclusive....

An index relation dim ker a†a− dim ker aa† = 1 is satisfied by the creation and annihilation operators a† and a of a harmonic oscillator. A hermitian phase operator, which inevitably leads to dim ker a†a − dim ker aa† = 0, cannot be consistently defined. If one considers an s + 1 dimensional truncated theory, a hermitian phase operator of Pegg and Barnett which carries a vanishing index can be ...
متن کاملPhase properties of a new nonlinear coherent state
We study phase properties of a displacement operator type nonlinear coherent state. In particular we evaluate the Pegg-Barnett phase distribution and compare it with phase distributions associated with the Husimi Q function and the Wigner function. We also examine number-phase squeezing of this state.
