Curvilinear Condensed Matter: Fundamentals and Applications
06 avr 2020 - 08 avr 2020 • Bad Honnef, Allemagne
Organisateur:
Wilhelm and Else Heraeus-Foundation seminar
Résumé:
Extending two-dimensional structures into the three-dimensional (3D) space has become a general trend in multiple disciplines, including electronics, photonics, plasmonics and magnetics. This approach provides means to modify conventional or to launch novel functionalities by tailoring curvature and 3D shape. In the case of 3D curved magnetic thin films and nanowires the physics is driven by the interplay between exchange and magnetostatic interactions, which contain spatial derivatives in their energy functionals. This makes both interactions sensitive to the appearance of bends and twists in the physical space. Theoretical works predict the curvature-induced effective anisotropy and effective Dzyaloshinskii-Moriya interaction resulting in a multitude of novel effects including magnetochiral effects (chirality symmetry breaking) and topologically induced magnetization patterning. Those 3D magnetic architectures are already proven to be application relevant for life sciences, targeted delivery, realization of 3D spin-wave filters, and magneto-encephalography devices to name just a few.

Workshop — Magnetic Small Angle Neutron Scattering – from Nanoscale Magnetism to Long‐Range Magnetic Structures
07 jui 2020 - 11 jui 2020 • Bad Honnef, Allemagne
Organisateur:
Wilhelm and Else Heraeus-Foundation seminar
Résumé:
This WE-Heraeus-Seminar focuses on the technique of magnetic small angle neutron scattering, which is one of the most important methods for magnetic microstructure determination in condensed-matter physics and materials science. Magnetic SANS provides access to bulk properties and yields, quite uniquely, information on the mesoscopic length scale (roughly 1-1000 nm). This is an important size regime where many macroscopic materials properties are realized. Currently, the magnetic SANS community can be roughly subdivided into two larger groups: the research of one group is anchored in the domain of condensed-matter physics with a focus on fundamental questions such as skyrmion crystals and topological spin structures, complex long-range-ordered spin structures, and vortex lattices in superconductors, while the second group of scientists employs the magnetic SANS method for scrutinizing nanoscale magnetism in terms of a micromagnetic continuum description; materials classes which are studied are e.g. permanent magnets, magnetic steels, nanoparticles and ferrofluids, or complex alloys. It is one of the central aims of this Heraeus seminar to bring both groups of researchers closer together by providing a stage for intra- and interdisciplinary scientific exchange. Besides, in view of the upcoming European Spallation Source, a further focus will be on future challenges related to neutron instrumentation, sample environment, and neutron data analysis.

Lattice‐based Quantum Simulation
21 jui 2020 - 24 jui 2020 • Ban Honnef, Allemagne
Organisateur:
Wilhelm and Else Heraeus-Foundation. Scientific organizers: Marzena Szymanska, Jacqueline Bloch, and Paulo V. Santos
Résumé:
Quantum simulation, the use of a controllable quantum system to mimic the operation of other, more complex quantum systems, provides a pathway for solving quantum problems with a complexity level not accessible by classical computers. This quantum technology is presently classified as a leading approach to solve complex many-body problems with potential applications in the design of new materials and drugs. The WE-Heraeus Seminar aims at bringing together experts in this emerging field to train students (at the MSc and PhD Levels) and young researchers interested in the area and discuss recent developments in a stimulating and informal atmosphere. The three-day seminar will consist of 17 tutorial-like lectures (50 min long) as well as 8 specialized talks (approx. 25 min long) covering topics such as (i) theoretical basis for quantum simulation, (ii) state-of-the-art of different platforms for quantum simulation (e.g., optical lattices of cold atoms, superconducting qubits, photonic simulators); (iii) novel concepts for scalable quantum processing and simulation exploring strongly coupled light-matter states, (iv) theoretical models for strongly correlated and dissipative systems, and (v) application of topological protection for robust quantum simulation. The scientific program will be complemented by poster sessions where the participants can present their results and discuss them with experts in the field. The exchange and cross-fertilization of ideas enabled by the seminar is expected to strengthen existing collaborations and foster new ones as well as enhance the visibility of the field.
