Abstract

We study a scheme of accelerated adiabatic quantum dynamics. This scheme was originally proposed by Masuda-Nakamura. The strategy of combining two opposite idea: infinitely-large timemagnification factor and infinitely-small growth rate (&#1013-) of adiabatic parameter was elucidated. We apply the proposed method to the system with electric and magnetic field and obtain regularization term, driving potential VF F and driving Hamiltonian HF F to accelerate the system. The driving potential VF F and the driving Hamiltonian HF F to be able to accelerate adiabatic transport of electron in the ground state trapped in the plane xy and electric field in the x direction and a constant magnetic field in y direction.
