Seminarium "Modeling of Complex Systems"

I will introduce the concept of universality: a tool for efficient description of the scattering properties of ultracold three-body systems. Furthermore, I will discuss the motivations behind implementing universal potential models in order to calculate the recombination losses in ion-atom samples. Then I will discuss how we can model an exemplary three-particle collision in a system interacting via the sum of two-body potentials. Briefly, I will mention the physics of Efimov states in considered systems.
