Lorentz流形上的随机量子化

Stochastic Quantization on Lorentzian Manifolds

Folkert Kuipers

摘要:

我们将Nelson的随机量子化嵌入到Schwartz-Meyer二阶几何框架中。其结果是(伪)黎曼流形上的量子力学的非微扰理论。在这种方法中,我们推导出大量的自旋为0的测试粒子在标量势,矢量势和重力下充电的随机微分方程。进而导出了相应的薛定谔方程。结果表明,在量子引力理论中,大质量标量粒子必须与引力共形耦合。最后,我们讨论了一些前景的随机框架。

英文摘要:

We embed Nelson's stochastic quantization in the Schwartz-Meyer second order geometry framework. The result is a non-perturbative theory of quantum mechanics on (pseudo)-Riemannian manifolds. Within this approach, we derive stochastic differential equations for massive spin-0 test particles charged under scalar potentials, vector potentials and gravity. Furthermore, we derive the associated Schrödinger equation. The resulting equations show that massive scalar particles must be conformally coupled to gravity in a theory of quantum gravity. We conclude with a discussion of some prospects of the stochastic framework.
