相对论性量子力学与静止标架瞬时形式动力学中的相对论性纠缠

Relativistic Quantum Mechanics and Relativistic Entanglement in the Rest-Frame Instant Form of Dynamics

David Alba, Horace Crater, Luca Lusanna

摘要:

本文在静止坐标系瞬时形式动力学的框架内,利用瞬时Wigner 3-空间,并借助于导出的非正则预测坐标描述粒子世界线,提出了一种新的相对论性量子力学表述.在该方法中,我们将非定域4-质心的Jacobi冻结数据和Wigner协变相对变量在一个抽象的(与标架无关的)内部空间中进行了处理,该内部空间的存在性由Wigner协变所暗示.形式主义照顾到相对论束缚态和散射的属性。对于\textit{relativistic localization problem}有一个自然的解决方案。非相对论极限导致标准的量子力学,但对质心的描述是冻结的。由于庞加莱生成元的\textit{non-locality},相对论纠缠的结果理论既是\textit{kinematically non-local and spatially non-separable}:这些性质,在非相对论极限中不存在,对非相对论量子非定域性的解释及其对基础问题的影响有不同的看法。

英文摘要:

A new formulation of relativistic quantum mechanics is proposed in the framework of the rest-frame instant form of dynamics with its instantaneous Wigner 3-spaces and with its description of the particle world-lines by means of derived non-canonical predictive coordinates. In it we quantize the frozen Jacobi data of the non-local 4-center of mass and the Wigner-covariant relative variables in an abstract (frame-independent) internal space whose existence is implied by Wigner-covariance. The formalism takes care of the properties of both relativistic bound states and scattering ones. There is a natural solution to the \textit{relativistic localization problem}. The non-relativistic limit leads to standard quantum mechanics but with a frozen Hamilton-Jacobi description of the center of mass. Due to the \textit{non-locality} of the Poincaré generators the resulting theory of relativistic entanglement is both \textit{kinematically non-local and spatially non-separable}: these properties, absent in the non-relativistic limit, throw a different light on the interpretation of the non-relativistic quantum non-locality and of its impact on foundational problems.
