Abstract

This project aims at the spatially resolved investigation of ultracold Rydberg physics (SpaRyP).

For this, our experimental apparatus is designed to combine

  • the ability of producing ultracold quantum gases of rubidium and lithium
  • with the controlled creation of individual Rydberg atoms
  • and with the temporally- and spatially-resolved detection of Rydberg ions via an ion microscope.

Research goals are the investigation of strongly-interacting quantum matter and the creation of (heteronuclear) Rydberg molecules either as a microscopic correlation probe for degenerate quantum gases or as a tool to study ultracold ion-atom scattering.

Characterizing and optmizing a high resolution ion microscope for ultracold ions (Master Thesis, beginning: from summer 2018)

Strongly interacting Rydberg atoms are predicted to undergo quantum phase transitons. We are currently setting up an ion microscope for the detection of single ions from a Rydberg excited quantum gas with a spatial resolution better than the size of a Rydberg atom. Within this thesis the microscope will be characterized via various aberration correction mechanisms. For this the experimental control and data aquisition system will be extended to include automatic feedback. The goal is to reach a spatial resolution such that the microscopic structure of strongly interacting quantum matter can be resolved.
