Single-atom detection with a quantum-controlled mechanical oscillator

Maxime Perdriat, Maciej Dziewiecki, Josef-Anton Agner +4

Using supersonic expansion, we create a time-gated, directional beam of Xe atoms with a narrow momentum distribution and detect their collisions with a levitated nanosphere cooled…

Intensity-dependent precision two-photon Doppler-free spectroscopy of Xe using narrow-bandwidth long-pulse deep-UV laser radiation

M. H. Rayment, R. Stech, F. Merkt

We report on a precision measurement of the transition wavenumber of Xe by Doppler-fre…

Combining laser cooling and Zeeman deceleration for precision spectroscopy in supersonic beams

Gloria Clausen, Laura Gabriel, Josef A. Agner +4

Precision spectroscopic measurements in atoms and molecules play an increasingly important role in chemistry and physics, e.g., to characterize structure and dynamics at long times…

Metrology in a two-electron atom: The ionization energy of metastable triplet helium ()

Gloria Clausen, Kai Gamlin, Josef A. Agner +2

Helium (He) is the ideal atom to perform tests of ab-initio calculations in two-electron systems that consider all known effects, including quantum-electrodynamics and nuclear-size…

Radiative and collisional processes in translationally cold samples of hydrogen Rydberg atoms studied in an electrostatic trap

Christian Seiler, Josef A. Agner, Pierre Pillet +1

Supersonic beams of hydrogen atoms, prepared selectively in Rydberg-Stark states of principal quantum number in the range between 25 and 35, have been deflected by 90,…

Measuring the polarization of electromagnetic fields using Rabi-rate measurements with spatial resolution: experiment and theory

J. Koepsell, T. Thiele, J. Deiglmayr +2

When internal states of atoms are manipulated using coherent optical or radio-frequency (RF) radiation, it is essential to know the polarization of the radiation with respect to th…

Imaging electric fields in the vicinity of cryogenic surfaces using Rydberg atoms

T. Thiele, J. Deiglmayr, M. Stammeier +4

The ability to characterize static and time-dependent electric fields in situ is an important prerequisite for quantum-optics experiments with atoms close to surfaces. Especially i…
