摘要
利用表象变换,把一个精确可解的含时两能级哈密顿量,变换成以瞬时本征态为基矢的不含时哈密顿量。在瞬时本征态为基矢下,量子绝热定理的物理图象变得非常清晰,有助于我们理解量子绝热定理。
Using representation transformation, we transform an exatly solvable two-level Hamiltonian into a time-independent one in the representation of the instantaneous eigenstate.In terms of the basis of the instantaneous eigenstate, the physical picture of the quantum adiabatic theorem becomes very clear, which will help us understand the quantum adiabatic theorem.
