Fundamental time asymmetry from nontrivial space topology | | F.R. Klinkhamer
; | | Date: |
26 Nov 2001 | | Journal: | Phys.Rev. D66 (2002) 047701 | | Subject: | gr-qc hep-ph hep-th | | Abstract: | It is argued that a fundamental time asymmetry could arise from the global structure of the space manifold. The proposed mechanism relies on the CPT anomaly of certain chiral gauge theories defined over a multiply connected space manifold. The resulting time asymmetry (microscopic arrow of time) is illustrated by a simple thought experiment. The effect could, in principle, play a role in determining the initial conditions of the big bang. | | Source: | arXiv, gr-qc/0111090 | | Services: | Forum | Review | PDF | Favorites | |
