Abstract: |
We study numerically the
Berry phase in semiconductor quantum dots (QDs)
that is induced by letting the dots to move adiabatically in a closed loop in
the 2D plane along the circular trajectory. We show that the Berry phase is
highly sensitive to the Rashba and Dresselhaus spin-orbit lengths. Based on the Finite
Element Method, we solve the Schr¨odinger equation
and investigate the evolution of the spin dynamics during the adiabatic
transport of the QDs in the 2D plane along circular
trajectory. Results of numerical simulations are discussed in detail,
indicating that this work might be used for the realization of solid state quantum information processing. |
