Two-dimensional magnetism in correlated systems

Descripción del proyecto

Fenómenos colectivos que afectan el comportamiento magnético de materiales 2D

El proyecto 2DMAGICS, financiado por las Acciones Marie Skłodowska-Curie, tiene como objetivo desarrollar técnicas teóricas precisas para describir el magnetismo y las interacciones magnéticas en sistemas electrónicos bidimensionales que podrían exhibir características magnéticas interesantes. En particular, el proyecto se dedica ahora a los semiconductores bidimensionales del grupo V, los dicalcogenuros de metales de transición, los semimetales nodulares estratificados y los sistemas de inteligencia artificial de superficie representados por estructuras atómicas regulares. Se espera que los resultados teóricos obtenidos en el marco del proyecto apoyen y estimulen actividades experimentales sobre nuevos materiales bidimensionales.

Objetivo

The 2DMAGICS project is aiming at solving actual problems related to the microscopic description, theoretical prediction, and dynamical control of magnetism and magnetic interactions of advanced two-dimensional materials and layered three-dimensional heterostructures. The main objects of investigation constitute two-dimensional group V semiconductors, transition metal dichalcogenides, layered nodal-line semimetals, and artificial surface systems represented by regular atomic structures localized on substrates. These materials will be described in terms of model Hamiltonians and studied using the state-of-the-art theoretical approaches and new theories that will be specially developed within the framework of the 2DMAGICS. Such a combination is to provide a realistic multiscale description of physical processes in the systems under investigation. The results expected will allow an accurate description of magnetic properties of realistic materials that exhibit different types of electronic and competing collective phenomena that affect magnetism. A special attention is given to magnetic properties of two-dimensional semiconductors, which are not typical in this class of materials. One of the promising problem concerns spin excitation phenomena in materials composed of heavy elements with strong spin-orbit coupling. On the other hand, the 2DMAGICS addresses practically important aspects, such as finding the possibilities for improvement and tunability of applied characteristics. Thus, an accurate description and control of already known and novel spin-spin interactions will allow to access nontrivial magnetic phases of technological importance. Realization of the 2DMAGICS is closely connected to the development of effective numerical methods, which is necessary to capture the essential role of competing collective electronic fluctuations that affect magnetic properties of materials.
