In this talk, I would like to present our latest result on the 1S-3S two-photon continuous wave spectroscopy of Deuterium atoms. [more]

Direct single-mode cw laser sources cover a broad wavelength interval for an almost unimaginable range of applications. [more]

Our understanding of the immediate response of matter to ionization is crucial for many fields. [more]

It has been known since 1927 that two modifications of hydrogen exist: para-H₂ and ortho-H₂. Pure para-H₂ can be prepared by leading a 1:3 para:ortho mixture of “normal” H₂ over a catalyst at low temperature. In 1933 Farkas and Sachsse [1] measured the rate coefficient of para-ortho H₂ conversion in gas mixtures with the paramagnetic open-shell molecules O₂, NO, and NO₂. [more]

Usually, rotational spectra of diatomics can be described by a handful of spectroscopic parameters. [more]

Search for violation of fundamental symmetries provides a unique opportunity for testing the Standard Model. Atomic and molecular experiments offer a low energy and comparatively inexpensive alternative to high energy accelerator research in this field. [more]

ARCNL in Amsterdam started in 2014 upon an initiative of ASML. [more]

Among all known isotopes, Thorium-229 has the lowest nuclear excited state, only 8.4 eV above the ground state. [more]

Over the years, cryogenic ion spectroscopy has established itself as a powerful technique for studying the structures and properties of biomolecules in the gas phase. [more]

X-ray science has evolved dramatically with the use of X-ray free electron lasers (XFELs) that can generate ultrashort X-ray pulses with unprecedented brilliance and coherence. [more]

The proton bond is a pivotal chemical motif with significant implications across science and technology, yet its quantum chemical description is challenged by nuclear and charge delocalization effects. [more]

The aluminium monofluoride molecule (AlF) is a promising candidate for laser cooling and trapping at high densities. [more]

Spin based properties, applications, and devices are commonly related to magnetic effects and to magnetic materials. [more]

Cryogenic ion traps combined with buffer gas cooling provide ideal conditions for preparing molecular ions in their vibrational ground states. [more]

Both days include an introductory morning session (10:00-12:00) and a hands-on afternoon session (14:00-16:00). While the first day (Tuesday) covers topics related to Experimental Control via EPICS, the second day (Wednesday) will focus on the FHI Compute Infrastructure and the Viper Supercomputer. [more]

Modern matter-wave experiments cover a broad mass range from single electrons to molecules consisting of hundreds of atoms. Levitated optomechanics promises to be-come a platform for matter waves of nanoparticles weighing a billion atomic mass units. [more]

One class of system where explorations of larger complexes is particularly instructive involves complexes of ions with water molecules. In these systems the cooperative nature of the hydrogen bond that are formed leads to large changes in the strengths of the ion-water interactions as more water molecules are introduced, and this, in turn, has a large effect on the spectroscopy. [more]

Research aiming at the quantification of molecular chirality by chiroptical techniques continues to attract a significant amount of interest in chemistry, physics, biology and pharmacology. [more]

Using a combination between both theoretical and experimental techniques, we are able to understand Feshbach resonances occurring in collisions between atoms and molecules, such as for instance Ne-H₂⁺ and Ne-HD⁺, at a fundamental level. [more]

After the discovery of nuclear fission, scientists in several different countries, including National Socialist Germany, brought the potential military applications of fission to the attention of political and military authorities. [more]
