共振二能级原子的有效场论

Effective field theory of resonant 2-level atoms

Mark Burgess

摘要:

用有效场论方法重新分析了唯象二能级原子。通过在实空间中引入Dicke-Jaynes-Cummings模型,实现了超越旋波近似的精确对角化。讨论了对称性和守恒量在理论中的意义,并将该模型与非平衡场论联系起来。解的结构提出了一个关于量子力学中旋波近似的问题。

英文摘要:

The phenomenological two-level atom is re-analysed using the methods of effective field theory. By presenting the Dicke-Jaynes-Cummings model in real space, an exact diagonalization is accomplished going beyond the rotating wave approximation. The meaning of the symmetries and conserved quantities in the theory is discussed and the model is related to non-equilibrium field theory. The structure of the solution raises a question about the rotating wave approximation in quantum mechanics.
