Analysis of linear ion Paul traps using 3-D FEM and the azimuthal multipole expansion

Popis výsledku v původním jazyce

Radiofrequency (RF) Paul traps are valuable in the design and in the operation of highly stablenoptical atomic clocks based on suitable trapped ions. The traditional setup involves a singlenion in an RF trap irradiated with a laser beam. The frequency of the laser light is then fine-tuned to match that of photons coming from an electronic transition in the atomic shell. Thenachievable frequency stability is about 10-17 for laser-cooled ions. However, the stability can benfurther improved by using heavy atoms (such as Thorium) and the more stable frequencies ofntheir nuclear transitions, and by setting up so-called Coulomb crystals, to improve the frequency measurement statistics by increasing the number of reference atoms. These techniques and their combination could reach relative stabilities beyond 10-20.
