Ultracold scattering processes in three-atomic helium systems

TL;DR

This paper reviews scattering processes in ultracold helium-atom systems, analyzing collision observables and the impact of interaction strength variations on scattering lengths in three-atomic helium systems.

Contribution

It provides a comprehensive review of helium-atom scattering observables and explores how changing interaction coupling affects scattering lengths in these ultracold systems.

Findings

Scattering observables for $^4$He--$^4$He$_2$ and $^3$He--$^4$He$_2$ collisions are characterized.

Variation of the coupling constant significantly influences the scattering length.

Results enhance understanding of ultracold helium-atom collision dynamics.

Abstract

We review results on scattering observables for $^4$He--$^4$He$_2$ and $^3$He--$^4$He$_2$ collisions. We also study the effect of varying the coupling constant of the atom-atom interaction on the scattering length.
