School on Disordered Elastic Systems

October 3-14, 2022

São Paulo, Brazil



Disordered elastic systems are ubiquitous and encompass a rich variety of systems ranging from amorphous solids, colloidal suspensions and network glasses to dislocation systems, biopolymer fibrous networks, confluent cell tissues and even strange metals and machine learning. Their comprehensive study has not only led to a much deeper understanding of traditionally difficult problems as the glass transition; it has also extended the theoretical frontier to incorporate new frameworks such as topological mechanics, non-reciprocal phase transitions and exciting mechanical metamaterials.

The school is intended for graduate students and researchers, and  will cover well-tested and successful theoretical methods used to study disordered elastic systems (critically-coordinated lattices, scaling theories and calculations for jamming and glasses in infinite dimension), as well as more recent developments that have attracted a lot of attention in the past few years (mechanical metamaterials, machine learning and biopolymer fibrous networks). In addition to the lectures, there will be one research seminar per week, to be given by an outstanding local researcher with expertise in the subject area of the school.

There is no registration fee and limited funds are available for travel and local expenses.
