Insulator spintronics – strong-coupling, coherence and entanglement
Magnetic insulators are extremely versatile materials. They’re used for fundamental research into magnetism and in real world devices. They have become a vital tool across many research disciplines to the extent that they are now micro-scale laboratories in their own right. The lack of charge currents in these materials allows for a very controlled environment where pure spin currents can flow and single magnons can be excited. However, nature is not so kind and the majority of magnetic insulators are a complex class of materials with many complications which must be understood.
This SPICE Young Research Leaders Workshop aims to bring together young scientific leaders who are interested in how magnetic insulators can be used to push the frontier of our understanding of basic science as well as technological frontiers such as spintronics and quantum computing. Specifically, this workshop will bring together researchers from the fields of insulator spintronics, magnon-polaritons and quantum magnetism to exchange ideas and discuss new ways in which magnetic insulators can be applied to fundamental research and applications.
In recent years the concepts of topology have entered strikingly all areas of physics, interlinking many previously unrelated areas of research. New topological materials and topological phases with exotic properties have been discovered at a rapid pace. However, these new phases are still being studied primarily within their own sub-disciplines of condensed matter, with not enough interaction among them to explore new emerging paths to hybrid and multifunctional advanced materials.
The workshop "Topology Matters" aims to bring together the top scientists in the fields of spintronics, superconductivity, topological insulators, and multiferroics in order to explore their connections via topology. The rapid developments in each of these fields, and the emerging importance of topology in all of them makes this workshop very timely.
Modern scientific research in condensed matter physics has been marked by a newly perceived role of the quantum nature of a spin in the most basic properties of materials. This breakthrough reflected itself in a new comprehension of fundamental physical symmetries, the concept of the topological classification of the quantum states properties, some of which are close to practical applications.
The aim of the SPICE workshop “Spin Dynamics in Dirac System” is to offer a platform for the knowledge exchange between diverse novel condensed matter domains such as topological insulators and superconductors, Weyl physics, topological Josephson junctions, spintronics in graphene, spin valves, spin-logic devices, quantum magnetism, spin lattices, frustrated magnets, spin liquids, non-trivial spin states, etc.
In contrast to equilibrium quantum systems, which exist in just a tiny corner of an immense configuration space, non-equilibrium quantum many-body systems can access the totality of configuration space and represent a rich resource for novel quantum states, including light-induced quantum-coherent phases of matter, topological phases and spin textures in solids and cold atom systems. Non-equilibrium many-body quantum dynamics is perhaps the last frontier in physics, where even the basic understanding is still lacking and a number of outstanding fundamental questions are wide open. However, there has been much recent progress in exploring these fundamental aspects on both theoretical and experimental sides.
This workshop aims to bring together junior group leaders in chemistry, physics, and astronomy, their academic administration leaders at German Universities, the Cottrell Scholar Collaborative(CSC) and the Fulbright Komission in a unique professional development workshop.
The workshop offers training for junior group leaders in Germany how to best implement evidence-based pedagogies, how to integrate research and teaching, new strategies for communicating science to the public, and to develop skills in time management, leadership, mentoring students, and networking. The workshop also engages the academic administration leaders in Germany in a dialogue how to leverage professional development for the future academic leaders and lifting the impact of the University.

During our last two workshops we had Yaroslav Tserkovnyak as a guest. Discussing Nonlocal Magnetization Dynamics in Ferromagnetic Hybrid Nanostructures with him was a great experience. We all learned a lot and are looking forward to further discussions.
The emerging field of antiferromagnetic spintronics focuses on making antiferromagnets active elements of spintronic devices. From an application point of view, it emphasizes how to read, manipulate, and store information in these systems robustly. From the basic science point of view, it exploits the larger range of spin physics in this material due to the higher complexity of the ordered phase and order parameters.
New connections with the current ferromagnetic spintronics research have created entirely new ways of rethinking spin phenomena in antiferromagnets, while still building on long standing pioneering works in antiferromagnetic materials.
Although some prevailing concepts map directly between these fields, in many important instances the intuition built in the ferromagnetic spintronics systems can lead us astray in the antiferromagnetic systems.
The recent successes in this new area and rapid theoretical developments make this the right time for a conference on the subject.
The field of magnon spintronics and the field of quantum magnetism have seen tremendous progress in recent years with many break-throughs in new concepts, new techniques, and new materials. Magnon spintronics has demonstrated electrical and thermal control over spin currents through magnetic insulators in contact with normal metals. Almost all this progress has been limited to a single material magnetic insultator YIG, hence limiting the outlook of the field. In Quantum Magnetism recent developments in scanning tunneling microscopy (STM) now permit probing and fabricating spin chains and many other artificial spin systems, providing a new ground to explore quantum magnetism phenomena, as well as a much larger spectrum of quantum magnetic materials to explore.

On July 4th and 5th the SPICE team and INSPIRE group had an internal group workshop in the picturesque village of Sörgenloch close to Mainz. In the nice atmosphere of Schloss Sörgenloch the SPICE team and INSPIRE group focused on team building processes and internal working strategies. The group also used the occasion to welcome Ulrike Ritzmann, as well as Bertrand Dupé and Marie Böttcher, who will join the group in October 2016. After a very successful first day, the group enjoyed the food and a variety of local wines served on the Schloss Sörgenloch terrace in the evening. On the second day of the workshop the group worked on presentation techniques and communication skills under the guidance of two coaches from an improvisational theater. We thank the participants for two beautiful and very successful days in Sörgenloch..
