长程相互作用玻色-爱因斯坦凝聚体的时间参数化

Time Parametrizations in Long-Range Interacting Bose-Einstein Condensates

Eiji Konishi

摘要:

广义相对论时空中的时间重参数化不变性不允许我们以机械的测量方式在量子力学中挑出一个时间。出于这个问题,我们研究这种规范不变性在基态的准静态粗粒态的远程相互作用封闭系统的相同或确定的,宏观的,时空不均匀的玻色-爱因斯坦凝聚体在热力学和牛顿极限。因此,我们发现,这是一个理论上的反例,这种规范不变性,除了适当的时间平移不变性,在粗粒度的水平。

英文摘要:

Time-reparametrization invariance in general relativistic space-time does not allow us to single out a time in quantum mechanics in a mechanical way of measurement. Motivated by this problem, we examine this gauge invariance in the ground state of the quasi-stationary coarse-grained state of a long-range interacting closed system of identical or identified, macroscopic, and spatiotemporally inhomogeneous Bose-Einstein condensates in the thermodynamic and Newtonian limits. As a result, we find that it is a theoretical counterexample of this gauge invariance, except for proper-time translational invariance, at a coarse-grained level.
