   Sammanfattning : In physics, toy models are often used in popular science contexts. Further, toy models have also been used to communicate some important principles of abstract phenomena qualitatively. One such example can be found in the 1989 Nobel laureate Wolfgang Paul’s Nobel lecture. LÄS MER

3. 2. Numerical simulation of the dynamics of a trapped molecular ion

   Författare :Avazeh Hashemloo; Claude Dion; Michael Drewsen; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diatomic molecular ion; linear Paul trap; rigid rotor; quantum rotational dynamics; wave-packet dynamics; time-dependent Schrödinger equation; stability;

   Sammanfattning : This thesis explores the dynamics of a heteronuclear diatomic molecular ion, possessing a permanent electric dipole moment, µ, which is trapped in a linear Paul trap and can interact with an off-resonance laser field. To build our model we use the rigid-rotor approximation, where the dynamics of the molecular ion are limited to its translational and rotational motions of the center-of-mass. LÄS MER
