We are currently designing and building a new experimental apparatus to study Rydberg states of multi-valence electrons.
Using our strong experience from the ERBIUM and the RARE experiment, we will set up a similar apparatus exploiting a transversal cooling chamber, Zeeman-slower, and a main chamber with a 5-beam MOT. The main chamber will also feature a versatile electric-field control to provide precise control over the Rydberg atoms.
Rydberg states in multi-electron atoms
Rydberg atoms are well-known for their exaggerated properties, especially their strong long-range interaction due to their extremely large dipole moment. In recent years, tremendous progress has been made, in both experimental as well as theoretical work, in studying their properties and first applications for quantum simulation. However, most of these studies concentrate on single- or two-electron systems like alkali, alkaline-earth or alkaline-earth-like atomic species. We will extent the studies to a new class of atomic complexity by investigating the multi-electron atom erbium.
