本文研究了任意双态隧道粒子在振荡外场作用下的局域化。对称系统局域化所需要的简并Floquet能级条件，对于对称性破缺的隧道系统可以大大放宽。动态不对称和静态不对称的协同效应，极大地扩展了局部化范围。这种推广同样适用于耦合到耗散环境的隧道系统。
The localization of a tunneling particle by means of an oscillating external field is examined for an arbitrary doublet of tunneling states. The condition of degenerate Floquet levels, required for localization in a symmetric system, can be substantially relaxed for tunneling systems with broken symmetry. A synergistic effect of dynamic and static asymmetry is found, which extends the localization regime substantially. This generalization equally applies to tunneling systems coupled to a dissipative environment.
