突现量子力学与突现对称

Emergent Quantum Mechanics and Emergent Symmetries

Gerard 't Hooft

摘要:

量子力学是“涌现的”,如果在局部确定性理论中对大尺度现象的统计处理需要使用量子算符。这些量子算符可以允许在基础确定性系统中不存在的对称变换。这样的理论可以自然地解释规范等价类(规范轨道)的存在,包括由一般坐标变换产生的等价类。因此,局域规范对称性和广义坐标不变性可能是涌现的对称性,这可能会为理解宇宙的平坦性问题带来新的途径。

英文摘要:

Quantum mechanics is 'emergent' if a statistical treatment of large scale phenomena in a locally deterministic theory requires the use of quantum operators. These quantum operators may allow for symmetry transformations that are not present in the underlying deterministic system. Such theories allow for a natural explanation of the existence of gauge equivalence classes (gauge orbits), including the equivalence classes generated by general coordinate transformations. Thus, local gauge symmetries and general coordinate invariance could be emergent symmetries, and this might lead to new alleys towards understanding the flatness problem of the Universe.
