de Broglie-Bohm方法中的密度矩阵

The density matrix in the de Broglie-Bohm approach

O. J. E. Maroney

摘要:

如果把密度矩阵当作单个系统的客观描述,就有可能把同样的客观意义赋予统计力学性质,如熵或温度,以及质量或能量等性质。它表明,德布罗意玻姆解释的量子理论可以一贯适用于密度矩阵作为一个描述的个别系统。由此产生的轨迹检查延迟选择干涉仪的情况下,贝尔似乎表明,这样的解释是不可能的。贝尔的论点被证明是基于不同的理解密度矩阵,这里提出的。

英文摘要:

If the density matrix is treated as an objective description of individual systems, it may become possible to attribute the same objective significance to statistical mechanical properties, such as entropy or temperature, as to properties such as mass or energy. It is shown that the de Broglie-Bohm interpretation of quantum theory can be consistently applied to density matrices as a description of individual systems. The resultant trajectories are examined for the case of the delayed choice interferometer, for which Bell appears to suggest that such an interpretation is not possible. Bell's argument is shown to be based upon a different understanding of the density matrix to that proposed here.
