Hydrogen Spectroscopy Project

Precision laser spectroscopy of atomic hydrogen and deuterium has long been used to determine physical constants and to test fundamental theories, owing to the simple structure of atoms allowing comparison with precise calculations. We are continuously improving constraints on these tests and shine light on possible discrepancies, such as the proton radius puzzle. At the moment, we are working towards measuring the 2S-6P transition in deuterium which allows for determination of the deuteron radius and further tests of quantum electrodynamics. To reach the required fractional uncertainty of a few parts in 1012 of the transition frequency, a sophisticated control over systematic effects such as quantum interference is required.

XUV Frequency Comb Project

We aim to perform high precision spectroscopy of He+ ions. Towards this goal we work on the XUV Frequency Comb generation in this project. We are looking for committed students of physics, who want to support our team as work students, Master students or PhD students.
Current projects are:


Bachelor project: Devlopment of low-noise diode lasers.
We offer a project for a Bachelor or Intern student. The goal of this project is to develop a low-noise diode laser system that is suitable for high precision spectroscopy experiments... more

Ion trap Project

Current projects are: a master project in precision laser spectroscopy with trapped ions to an interested student, who is wiling to invest a significant effort. The purpose of this experiment is to open a new route for testing quantum electrodynamics by comparing experimental results with theoretical calculations.
Most of the required hardware and many years of experience in this field exists at the Max-Planck institute of quantum optics at Garching. We have an excellent research environment with services and infrastructure support that can considerable speed up experimental work.
