Unruh Effect and the Spontaneous Breakdown of the Conformal Symmetry
Fulling-Davies-Unruh effect conformal relativity accelerated frames
2011/3/3
We revise the Unruh effect (vacuum radiation in uniformly relativistic acceler-ated frames) in a group-theoretical setting by constructing a conformal SO(4,2)-invariant quantum field theory and its sp...
Spontaneous Symmetry Breaking during Formation of ZnO Nanocrystals
Crystal structure Growth models Nanomaterials Spontaneous symmetry breaking
2011/3/4
Systemic symmetry is introduced into our work to investigate the symmetries of different ZnO nanocrystals. Result shows that systemic symmetries obey the law of spontaneous symmetry breaking during th...
