### ATTOELECTRONICS

Dr. Eleftherios Goulielmakis

Attoelectronics is a term coined to describe the capability of triggering, as well as driving the motion of electrons within tens to thousands of attoseconds (1 as =10

^{-18}sec); that is, on the native time scale of electronic processes in the fundamental constituents of matter--i.e. in atoms, molecules or more complex quantum systems such as a nanoparticles or nanostructures. [more]### ANTIMATTER SPECTROSCOPY

Dr. Masaki Hori

The Research Group 'antimatter spectroscopy', since 2013 financed by an ERC Starting Grant, carries out precise laser and microwave spectroscopy of atoms containing antimatter, and develops new techniques to manipulate antimatter particles using superconducting radiofrequency traps. ... [more]

### MUONIC ATOMS

Dr. Randolf Pohl

Our research is dedicated to laser spectroscopy of muonic atoms and ions. These are exotic systems in which one negative muon replaces the atoms' electrons. Muons are very the heavy brothers of electrons. Both are point-like particles, but muons are about 200 times heavier. Therefore, muons get on average 200 times closer to the atomic nucleus than electrons do.This makes the muon much more sensitive to the properties of the nucleus. [more]

### Entanglement of Complex Quantum Systems

Prof. Dr. Norbert Schuch

The research group "Entanglement of Complex Quantum Systems" works at the interface between strongly correlated many-body systems and quantum information theory. Strongly correlated quantum systems exhibit a wide range of exotic physical phenomena, such as topologically ordered phases with quantised egde currents and exotic excitations, which arise from their intricate entanglement structure.

Dr. Christian Groß

The project "Rydberg Dressed Quantum Many-Body Systems (RyD-QMB)", funded by a Starting Grant of the European Research Council, aims to combine two established research fields in atomic physics – ultracold atomic quantum gases and Rydberg atoms – to experimentally explore new aspects of quantum many-body physics.

[more]### Otto Hahn Group Quantum Networks

Dr. Andreas Reiserer

A future quantum network will consist of quantum processors that are connected by quantum channels, just like conventional computers are wired up to form the Internet. In contrast to classical devices, however, the information that can be encoded in a quantum network grows exponentially with the number of nodes, and entanglement of remote particles gives rise to non-local correlations.
