AI总结:

通过将量子Cauchy-动量方程转换到Lagrangian参考系,移除量子势项,推导出Klein-Gordon系统的局部随机de Broglie-Bohm解释,并引入动量等变概念替代失效的二阶Bohm-Newton运动方程。

摘要:

量子力学中的非定域性问题,可以通过考虑四维时空中相对论协变扩散来潜在解决。由Klein-Gordon方程描述的随机粒子被证明在时空坐标中经历经典扩散过程,这是通过将量子Cauchy-动量方程转换到Lagrangian参考系中观察到的。由于在该变换下移除了量子势项,沿粒子轨迹的动量传播方程呈现经典形式。随后可以推导出Klein-Gordon系统的局部随机de Broglie-Bohm解释。我们还引入了动量等变概念,以替代由于随机Lagrangian导数的非线性项而失效的二阶Bohm-Newton运动方程。

英文摘要:

The issue of non-locality in quantum mechanics can potentially be resolved by considering relativistically covariant diffusion in four-dimensional spacetime. Stochastic particles described by the Klein-Gordon equation are shown to undergo a classical diffusion process in spacetime coordinates, which is seen by transforming the quantum Cauchy-momentum equations to a Lagrangian frame of reference. Since the quantum potential term is removed under this transformation, the equations for momentum propagation along particle trajectories assume a classical form. A local stochastic de Broglie-Bohm interpretation for the Klein-Gordon system can subsequently be derived. We also introduce the concept of momentum equivariance to replace the second-order Bohm-Newton equations of motion, which break down due to non-linear terms of the stochastic Lagrangian derivative.
