The topic of functional materials at surfaces covers a wide range of material classes and length scales, from single surface-adsorbed organic molecules to extended 2D structures, and thus research areas. What these areas all have in common is the goal to understand the physics that ultimately defines the properties of these materials, and eventually to learn how to modify these properties in a controlled and reproducible manner to devise materials optimized for applications. One enormously powerful toolbox to achieve this is scanning probe microscopy (SPM). Over the past 40 years since its invention, SPM has evolved from a mere imaging technique to a tool that can provide information on structural, electronic, optical, and magnetic properties, and even facilitate the manipulation of individual adsorbates, all at the atomic level. These advances over the past decades have sparked tremendous progress not only in our understanding of the physics of such low-dimensional systems, but also in our ability to build structures with specifically tailored functionality. While the main focus of this seminar will be scanning probe based approaches, we want to also bridge the gap to alternative and complementary high-resolution characterization techniques.

Storage and effective usage of renewable energy will be one of the major challenges our society will face in 21th century. This century will witness a major transformation in how energy is acquired, stored, and utilized globally. Neutron scattering contributes significantly to the advancement of energy storage technologies by providing detailed insights into the structural and dynamic properties of materials. This information is instrumental in designing and improving materials for more efficient, durable, and sustainable energy storage solutions.

Machine Learning methods have recently found widespread use in areas of atomistic modelling, mainly focusing on developing surrogate models for the potential energy surface with superior computational efficiency while retaining first principles accuracy. However, approaches to learning observable properties directly are just emerging and are challenged by several issues, which we intend to address in the workshop. The event is meant to support the development of a new collaborative, international network connecting different fields of research and integrating the young researchers community with the help of a scientifically diverse, interactive workshop.

Emergent phenomena are the essence of condensed-matter physics and at the same time what makes the behavior of correlated materials appealing for applications. They are, however, hard to understand at a fundamental level. It is the interplay of several competing interactions — none of which can be treated as a mere perturbation, leading to the emergence of effective interactions — that makes their description a grand challenge. Addressing this problem requires mastery of a wide spectrum of theoretical concepts, ranging from materials modeling using first-principles approaches to advanced many-body methods based on dynamical mean-fields, stochastic simulations and renormalization techniques. The concepts of symmetry, topological invariance and the classification of transitions between phases are of crucial importance to bring order to the plethora of observed phenomena.

The goal of this year’s school is to provide students with an overview of the state-of-the-art in the field of emergent phases in strongly correlated systems and the many techniques used to investigate them. The program will start with fundamental models and concepts, introducing the Hubbard and Anderson Hamiltonians and their physics, and providing an overview of field-theoretical aspects of condensed-matter physics. More advanced lectures will introduce symmetries, Berry phases and topological quantum matter. The focus will then turn to emergent phenomena: superconductivity, conventional and non-conventional, Kondo and heavy-fermion behavior, Kosterlitz-Thouless transitions, Mott phases, orbital-ordering, and quantum phase transitions. The topics will be treated both from the view point of simple models and that of real materials, with an outlook on materials design from the theoretical and experimental viewpoint. The theoretical approaches covered will go from density-functional-theory-based methods to dynamical mean-field theory and quantum Monte Carlo. Experimental lectures will cover phenomena under normal and extreme conditions.

The conference is organized by the Jülich Centre for Neutron Science (JCNS), Forschungszentrum Jülich.

The JCNS Workshop 2024 will be held in Tutzing, Germany on October 8th to 11th, 2024 and it will bring together experts in neutron scattering and other scattering techniques to discuss present status, ongoing developments as well as future perspectives in the field of functional interfaces.

Interfaces play an important role in a variety of applications, both in soft matter, quantum materials as well as in the food industry and energy storage devices. In particular, functional interfaces are a cross-cutting area of research with neutrons and other scattering techniques in science and industry and they offer a unique opportunity to create a networking event with an interdisciplinary scientific program at the cutting edge of science and technology.
