High honors for TopDyn Researchers

The IEEE Magnetism Society and the German Physical Society has announced the recipients of their society awards in 2023. In this year, three of these prestigious awards go to TopDyn researchers.


IEEE Achievement Award for Prof. Burkard Hillebrands

The 2023 IEEE Achievement Awards goes to Prof. Dr. Burkard Hillebrands from the University of Kaiserslautern.                                                                                                                                                  The IEEE Achievement Award recognizes outstanding accomplishments and contributions to the field of Magnetics. Prof. Hillebrands is the first German scientist to receive this high honor. The award ceremony will be held during the IEEE INTERMAG conference in May 2023 in Sendai, Japan.


Prof. Mathias Kläui becomes IEEE Fellow in 2023

IEEE Board of Directors awarded Prof. Dr. Mathias Kläui, University of Mainz, the status of an IEEE Fellow for his contribution to the next generation magnetic solid-state memory, logic and sensor devices.
IEEE Fellow is a distinction reserved for select IEEE members whose extraordinary accomplishments in any of the IEEE fields of interest are deemed fitting for this prestigious grade elevation. The total number selected in any one year does not exceed 0.1% of the total voting Institute membership.

Gaede Prize for Dr. Benjamin Stadtmüller

The Gaede Prize for Vacuum Science and Technology goes to Dr Benjamin Stadtmüller from the University of Mainz and Kaiserslautern in recognition of his outstanding and pioneering work on controlling optical and electronic properties of hybrid interfaces with newly developed, time-resolved and surface-sensitive measurement methods.
The Gaede Prize is financed by the Gaede Foundation and awarded by the DPG. It was endowed by Dr Manfred Dunkel in 1985 and has been awarded annually since 1986. Dr Stadtmüller will receive the award in March 2023 during the DPG Spring Meeting of the Condensed Matter Section in Dresden.

TOPO 2022 – International Workshop on Topological Structures in Mainz

In September 2022, a team around M. Kläui organized the International Workshop on Topological Structures TOPO 2022 at the Institute of Molecular Biology at the University of Mainz. This workshop is the 7th installment of the TOPO conference series focusing on topological solitons, topological spin structures, topological textures in antiferromagnets and ferroelectrics, as well as excitations in these systems.                                                            Despite the travel challenges of the still ongoing COVID-19 pandemic, we were able to attract contributions from leading experts in the field from around the world joining the workshop large in person. The high number of up to 70 on-site participants fostered intense discussion between all participants of the workshop and made the workshop a lively and successful event.

Long-range information transport in antiferromagnets

JGU physicists discovered that canted antiferromagnets are suitable for transporting spin waves over long distances. This offers a whole new class of materials, which allow for magnon transport in insulating system. These materials have the potential to significantly increase computing speed compared to existing devices and at the same time greatly reduce waste heat.

TopDyn online seminar: postponed; new date will be announced soon

Merging spintronics and quantum thermodynamics to harvest ambient thermal energy

Dr Martin Bowen

French National Centre for Scientific Research | CNRS
Institute of Physics and Chemistry of Materials at Strasbourg (IPCMS)

I will present a novel concept that blends spintronics and quantum thermodynamics to generate
electricity. This concept is invoked to explain our experimental observations of electrical generation
across oxide [1] and molecular spintronic devices [2] that comprise paramagnetic centers
sandwiched between electrodes with full transport spin polarization. The presence of so-called
quantum resources [3,4], leading to a source of work of quantum origin called ergotropy, appears [2] to be manifest in sub-kBT spectral features, as well in an apparent signature of a phase transition of
the spin fluctuations on the paramagnetic centers. I will discuss our present research tracks to better
understand this spintronic quantum engine. General info may also be found at

Collaborative project of quantum computer developers

New ATIQ project with funding from the German Federal Ministry of Education and Research has a total volume of EUR 44.5 million (December, 2021)

Quantum computers promise unprecedented computing power for applications where conventional data processors based on "zeros and ones" fail. In the new Trapped-Ion Quantum Computer for Applications project, 25 partners from research institutions are now working together with industrial partners to develop quantum computer demonstrators implemented together with users of quantum computers. The partners will tackle major technical challenges to realize quantum computer demonstrators made in Germany and to facilitate 24/7 access for users.

The ATIQ project is an extension of the IQuAn project.
