Previous Experiments

Cavity Quantum Optics
Our team is exploring applications of optical micro- and nano-cavities in the fields of quantum optics with solid-state systems, optical sensing, microscopy, and spectroscopy. more
Ion Traps
A careful analysis of the excitation dynamics reveals that excitation is accompanied by a significant ionization probability. We therefore plan to operate the ion trap such that the resulting He++ ions remain stored as signature for successfull excitations. more
Frequency combs in the Extreme Ultraviolet (XUV)
Femtosecond laser optical frequency combs have revolutionized the measurement of optical frequencies and enabled optical atomic clocks. The same comb techniques are employed to control the carrier-envelope phase and thus the waveform of ultrafast laser pulses, which has led to the generation of single attosecond pulses. more
The Hydrogen 1S-3S Transition
Similarly, to the 2S-4P experiment, the purpose of measuring the 1S-3S transition freuquency in atomic hydrogen is to test the theory of Quantum Electrodynamics (QED). more
The Hydrogen 2S-nP Transitions
We are determined to measure a series of transition frequencies between the metastable 2S state, that acts as the ground state here, and the nP levels in atomic hydrogen. more
Dual Comb Molecular Spectroscopy
We are exploring advanced photonics tools, such as optical frequency combs and new techniques from fiber-optical telecommunications, to reach beyond the limits of what has been possible in the past. more
Experimental Quantum Physics
Our group performs experiments on foundations of quantum physics, quantum information and communication. We are located at the LMU University of Munich and at the Max-Planck Institute of Quantum Optics in Garching. more

Previous Experiments:

Frequency Combs
Frequency combs can be generated with a mode-locked laser that emits a train of laser pulses. One can think of the comb lines as the longitudinal cavity modes of that laser. more
The Hydrogen 1S-2S Transition
Atomic hydrogen was crucial for the development of quantum mechanics because of its simplicity. Narrowband lasers whose frequency can be precisely tuned to one of the hydrogen lines have been available for about fifty years now. more
Frequency Combs to Measure Cosmic Velocities
Indirect methods, such as the radial velocity method, have been used for the discovery of many exoplanets.The frequency accuracy of a frequency comb is very helpful to achieve this goal. more

Lamb shift in Muonic Hydrogen
We investigate fundamental properties and interactions of light exotic systems, especially muonic atoms such as µH and µD. more
