SC Zhang的拓扑场论(Topological Field Theory)论文,其中引入Chern-Simons term的有效理论将拓扑绝缘体推广到了4维等更高维度,如前所述,Bernevig & Taylor Hughes的‘Topological Insulator and Superconductor’可以作为这篇文章的补充内容。

It is shown that topological massive gravity augmented by the triadic gravitational Chern-Simons first order term is a curved a pure spin-2 action. This model contains two massive spin-2 excitations. However, since its light-front energy is not semidefinite positive, this double CS-action does ...
Chern-Simons termWe perform the complete bosonization of 2+1 dimensional QED with one fermionic flavor in the Hamiltonian formalism. The fermion operators are explicitly constructed in terms of the vector potential and the electric field. We carefully specify the regularization procedure involved in ...
The charge is split into two contributions (/δQNoether ) = (/δQNoether )Ein-Max + (/δQNoether )H , (2.7) where the first term on the right hand side comes from the Einstein-Maxwell part of the Lagrangian while the second one arises from the Chern-Simons terms. The explicit form...
model with the Chern-Simons term, which 5 may be obtained through several steps with the three definitions of the canonical, the total, and the reduced Hamiltonian in the usual Dirac formalism of constrained systems [1]. Furthermore, this model has only four constraints in the symplectic ...

规范场里面本来CS term就是规范不变的,只不过它破坏CP,所以基本法相互作用里面不准它出现~另外这和GR怎么扯上关系的?它是个拓扑项和度规decouple是没错,但怎么就成了一种新的相互作用? 来自iPhone客户端7楼2013-10-19 00:15 收起回复 登录百度帐号 下次自动登录 忘记密码? 扫二维码下载贴吧客户端 下载贴吧APP...
