含时广义振子的不变算子与海森堡算子

Invariant Operators vs Heisenberg Operators for Time-Dependent Generalized Oscillators

Sang Pyo Kim

摘要:

研究了满足量子Liouville-von Neumann的不变算子与满足Heisenberg方程的Heisenberg算子之间的关系。对于含时广义振子,我们发现不变的运营商,被称为Ermakov-Lewis不变量,在一个复杂的经典解决方案,从该演化运营商派生,并获得海森堡位置和动量运营商。物理量,如关联函数计算使用不变算子和海森堡算子。

英文摘要:

We investigate the relation between the invariant operators satisfying the quantum Liouville-von Neumann and the Heisenberg operators satisfying the Heisenberg equation. For time-dependent generalized oscillators we find the invariant operators, known as the Ermakov-Lewis invariants, in terms of a complex classical solution, from which the evolution operator is derived, and obtain the Heisenberg position and momentum operators. Physical quantities such as correlation functions are calculated using both the invariant operators and Heisenberg operators.
