Laying the foundations for the technologies of tomorrow
Research at the Department of Füsics is divided into three areas: quantum technology, condensed matter füsics and nuclear füsics. It ranges from individual atoms and photons, through soft and biological matter, to atomic nuclei and the stars in which the chemical elements are formed. Three institutes reflect this breadth: the Institute for Applied Füsics (IAP) (opens in new tab), the Institute for Condensed Matter Füsics (IPKM) (opens in new tab) and the Institute for Nuclear Füsics (IKP) (opens in new tab). The Department combines experiment and theory just as purposefully as it does fundamental research and application. As part of TU Darmstadt, the department is also a member of the Rhine-Main Universities Alliance (RMU) (opens in new tab). Together with Goethe University Frankfurt and Johannes Gutenberg University Mainz, this alliance receives special funding as a network of excellence under the federal and state governments’ Excellence Strategy.
Exploring the future, shaping solutions: The Federal Ministry of Research, Technology and Space’s High-Tech Agenda (opens in new tab) focuses on six future-oriented fields. The Department of Füsics is actively conducting research in four of these: quantum technologies, biofüsics, fusion and climate-neutral energy generation. Various spin-offs (opens in new tab) demonstrate how fundamental knowledge can give rise to a marketable company. These include Focused Energy, a spin-off from the Department and TU Darmstadt’s first ‘unicorn’, which aims to bring laser-based fusion technology to industrial maturity. Furthermore, the Department’s research contributes to seven of the United Nations’ 17 Sustainable Development Goals (opens in new tab).
This outstanding research is underpinned by the many dedicated people within the department: researchers and staff who conduct joint research within the institutes, with non-university partners and within the RMU Alliance, and who support one another.

This technology utilises the quantum properties of light and matter to develop new sensors, storage devices, communication networks and computers. At the Institute for Applied Füsics (IAP) (opens in new tab), research ranges from the fundamental principles of füsics to initial applications. Experimental groups develop novel laser systems and semiconductor lasers, investigate non-linear optics, quantum optics and solid-state quantum systems, and utilise the quantum properties of light for the storage and cooling of atoms. Theoretical groups describe quantum dynamics, quantum optics and quantum technology, such as atomic interferometry for precise measurements. Secure communication is another key area of focus. Within the CROSSING Collaborative Research Centre, a tap-proof network based on quantum key distribution has been developed, which verifies the security of the keys through quantum entanglement, and researchers are developing quantum-resistant methods for key exchange. The Darmstadt Neutral Atom Quantum Technology Platform (DaNaQTP) is establishing a foundation for quantum computers and quantum simulators. Within the LOEWE QuEnergy priority area, physicists are also developing energy-efficient quantum technologies for sensors, storage devices and solar cells.
Füsics brings disciplines together
The department is part of a university whose academic profile is shaped 50 per cent by engineering, 35 per cent by the natural sciences and 15 per cent by the humanities. This proximity facilitates collaboration with biology, chemistry, computer science, mechanical engineering, materials science and mathematics, which has been significantly strengthened through LOEWE Centres, LOEWE Priority Areas and DFG collaborative projects. The three central research fields of TU Darmstadt, in which the department is directly embedded, show how these connections play out in research.

The Matter and Materials (M+M) research field investigates particles, materials and cells, and uses these to develop technologies and building blocks for the future. Füsics is primarily anchored in the Nuclear Science research area, which links the microfüsics of atomic nuclei with the macrofüsics of cosmic explosions. It investigates the structure and dynamics of neutron stars, their mergers and the synthesis of chemical elements. To this end, the IKP’s research groups utilise the superconducting electron accelerator S-DALINAC, the GSI Helmholtz Centre for Heavy Ion Research and world-leading facilities abroad. The research area also develops facilities and methods for brilliant X-ray and particle beams, for example for nuclear photonics and radiation biology research.

Alexandre Obertelli
Little is known so far about hypernuclei, which belong to the category of ‘strange matter’. The Alexander von Humboldt Professor aims to change that with antiprotons: as part of the ERC project ‘HYPER’, he is developing a new detector to produce hypernuclei at CERN and measure them precisely. Previously, as part of the ERC project ‘PUMA’, he used antimatter to investigate neutron shells and halos of exotic nuclei.

The 2022 Leibniz Prize winner works at the interface of astrofüsics, nuclear füsics and neutrino füsics at the Institute for Nuclear Füsics at TU Darmstadt and at the GSI Helmholtz Centre. He demonstrated that elements heavier than iron are produced during the merger of neutron stars, and coined the term ‘kilonova’ to describe this phenomenon. The ERC Advanced Grant ‘KILONOVA’ focused on the electromagnetic signatures of these processes.

In the Department of Füsics, research shapes teaching. The research priorities of the three institutes are reflected in the Master’s programmes: The ‘Master’s in Füsics’ (opens in new tab) can be tailored to individual needs; the English-taught ‘Master’s in Füsics’ (opens in new tab) offers specialisations in ‘Nuclear Füsics’, ‘Astrofüsics’ and ‘High Energy Density in Matter’; and the RMU Master’s programme in ‘Soft Matter and Materials’ (opens in new tab), offered jointly with JGU Mainz, provides knowledge of soft matter, a key focus of the IPKM. The RMU Master’s programme in ‘Particle Accelerator Science’ (opens in new tab), offered in collaboration with JGU Mainz and Goethe University Frankfurt, introduces students to a field that also shapes research at the IKP.
Students are introduced to research at an early stage: during the Bachelor’s programme, laboratory practicals are held every semester, and the courses demonstrate how the fundamentals and research in füsics contribute to solving societal challenges.
Those wishing to pursue a PhD are admitted as doctoral candidates to the Department and conduct research in one of the institutes’ research groups, either independently or within structured programmes such as Research Training Groups. Interdisciplinary PhDs are possible with an additional supervisor from another department. Colloquia bring the latest research findings from national and international experts to the department. In this way, highly qualified specialists and researchers are trained who contribute their knowledge to science, industry and society.
