线性正则变换和量子相位:统一的正则和代数方法

Linear canonical transformations and quantum phase:a unified canonical and algebraic approach

T. Hakioglu

摘要:

本文从Schwinger幺正正则基的角度研究了广义线性量子正则变换的代数。制定的量子相位问题的理论内的量子正则变换,特别是与广义量子作用角相空间形式主义的建立,它表明,量子相位问题的概念基础在于量子正则变换在量子相空间中的代数性质。研究了一类具有动力学对称性的哈密顿系统的Wigner函数在广义作用角酉算符对中的表示。将这种广义正则形式应用于量子谐振子,研究了幺正量子相位算符和作用角Wigner函数的性质。

英文摘要:

The algebra of generalized linear quantum canonical transformations is examined in the prespective of Schwinger's unitary-canonical basis. Formulation of the quantum phase problem within the theory of quantum canonical transformations and in particular with the generalized quantum action-angle phase space formalism is established and it is shown that the conceptual foundation of the quantum phase problem lies within the algebraic properties of the quantum canonical transformations in the quantum phase space. The representations of the Wigner function in the generalized action-angle unitary operator pair for certain Hamiltonian systems with the dynamical symmetry are examined. This generalized canonical formalism is applied to the quantum harmonic oscillator to examine the properties of the unitary quantum phase operator as well as the action-angle Wigner function.
