T-REQS LAB

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 experiments, 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 extend the studies to a new class of atomic complexity by investigating the multi-electron atom erbium.

Optical Tweezer Arrays of Erbium Atoms

Now published in the journal “Physical Review Letters”, and featured in Physics Magazine as an Editors' Suggestion! The T-REQS Lab presents the first successful trapping of single erbium atoms in an array of optical tweezers, marking a significant milestone in the use of erbium for quantum simulation.
