高阶理论及其与非对易性的关系

Higher Order Theories and its Relationship with Noncommutativity

Oscar Sánchez-Santos, José David Vergara

摘要:

本文用微扰的方法给出了非对易性与高阶时间导数理论之间的关系。本文将陈-西蒙斯量子力学推广到高阶时间导数。当我们投射到低能态时,这个模型以一种自然的方式呈现出非对易性。与通常的模型相比,我们的系统呈现出非对易性,而不需要采取强场的限制。我们用非对易变量的波普位移将理论量子化,得到了一个没有负能量的谱。此外,我们还将模型推广到高阶导数和变相依参数的非交换性。

英文摘要:

We present a relationship between noncommutativity and higher order time derivative theories using a method perturbative. We introduce a generalization of the Chern-Simons Quantum Mechanics for higher order time derivatives. This model presents noncommutativity in a natural way when we project to states of low energy. Compared with the usual model, our system presents noncommutativity without the necessity of taking the limit of strong field. We quantized the theory using a Bopp's shift of the noncommutative variables and we obtain an spectrum without negatives energies. In addition we extend the model to high order derivatives and noncommutativity with variable dependent parameter.
