Abstract (en)

[origin: WO02073229A1] The invention relates to a method for calculating parameters for frequency and/or amplitude modulated electromagnetic pulses for adiabatic transfer steps in a quantum mechanical system. The dynamic steps of the quantum mechanic system comprise a Hamilton Operator (H(t)) of a current system of co-ordinates. The inventive method consists of the following steps: a) transformation of the Hamilton Operator (H(t)) of a current system of co-ordinates into a subsequent system of co-ordinates for describing the time dependency of the change in direction of the Hamilton Operator (H(t)); b) determination of the automatic commutation of the Hamilton Operator (H(t)) at a time t and the Hamilton Operator (H(t')) at a time t' in the corresponding system of co-ordinates, whereby a differential equation system is obtained; c) calculation of the parameters from the differential equation system thus obtained.
