The upper bound function of nonadiabatic dynamics in parametric driving quantum systems
Zhang Lin†, , Liu Junpeng
       

The parametric paths of different driving schemes in the parameter space of Bloch sphere. The driving parameters are ω = 0.02 ω 0 , α 0 = 0.2 , (I) ν / ω = 1 / 2 , α 1 / α 0 = 1 / 2 ; (II) ν / ω = 2 / 1 , α 1 / α 0 = 1 / 2 ; (III) ν / ω = 1 / 2 , α 1 / α 0 = 3 / 2 ; and (IV) ν / ω = 2 / 1 , α 1 / α 0 = 3 / 2 .
