我们考虑一类自旋网络,其中某个集合中的每个自旋通过伊辛耦合与一组中心自旋相互作用,并且控制同时作用于所有自旋。由于网络的置换对称性,系统不是全局可控的,但它显示了底层希尔伯特空间的不变子空间。如果系统在每个子空间上都是可控的,则称系统是子空间可控制的。我们刻画了这类系统的不变子空间和动力李代数,并证明了在任何情况下的子空间能控性。
We consider a class of spin networks where each spin in a certain set interacts, via Ising coupling, with a set ofcentralspins, and the control acts simultaneously on all the spins. Due to the permutation symmetries of the network, the system is not globally controllable but it displays invariant subspaces of the underlying Hilbert space. The system is said to besubspace controllableif it is controllable on each of these subspaces. We characterize the given invariant subspaces and the dynamical Lie algebra of this class of systems and prove subspace controllability in every case.
