S. G. Schirmer, I. C. H. Pullen, A. I. Solomon

摘要:

考虑了有限能级量子系统受外部控制的动力学李代数的识别问题,特别强调了不完全可控的系统。特别地,证明了具有等间距能级和均匀跃迁偶极矩的N能级系统的动力学李代数,当$N=2\ell+1$为$so(N)$的子代数,当$N=2\ell$为$sp(\ell)$的子代数.建立了获得$so(2\ell+1)$或$sp(\ell)$的一般条件。

英文摘要:

The problem of identifying the dynamical Lie algebras of finite-level quantum systems subject to external control is considered, with special emphasis on systems that are not completely controllable. In particular, it is shown that the dynamical Lie algebra for an N-level system with equally spaced energy levels and uniform transition dipole moments, is a subalgebra for $so(N)$ if $N=2\ell+1$, and a subalgebra of $sp(\ell)$ if $N=2\ell$. General conditions for obtaining either $so(2\ell+1)$ or $sp(\ell)$ are established.
