论文摘要
Magnus的扩张用于识别有效的哈密顿人描述更复杂问题的粗粒动力学。在这里，我们将此方法应用于由AC和AC场驱动的两级系统。我们仅由于粗晶状而导致了汉密尔顿的对角线和偏对角条目的Stark和Bloch-siegert Shifs。
Magnus expansion is used to identify effective Hamiltonians describing the coarse-grained dynamics of more complex problems. Here, we apply this method to a two-level system driven by an and AC field. We derive Stark and Bloch-Siegert shifs of both diagonal and off-diagonal entries of the Hamiltonian as a result of coarse-graining only.
