Dates: January 9 - 13, 2023
Venue: HIM lecture hall, Poppelsdorfer Allee 45, Bonn
Organizers: Irene Fonseca (Carnegie Mellon), Valeriy Slastikov (Bristol), Arghir Zarnescu (BCAM)

Many recent and spectacular technological advances are driven by the developments of novel complex materials with extraordinary and unique features. The adequate mathematical models are essential for the discovery and systematical study of the properties of these complex materials. There exists a number of well-accepted models for complex materials with well-understood mathematical challenges, for instance Oseen-Frank and Landau-de Gennes models for liquid crystals, Landau-Lifschitz and Brown models for magnetic materials, to name just a few. However, contemporary active investigations in physics, for instance, focus on heterogeneous or layered materials where multiple components with different properties are combined at appropriate scales. The main aim of this workshop is to bring together mathematicians and scientists working in various areas of materials science and applied mathematics in order to identify the main challenges posed by the modelling and analysis of complex materials.
