Training overdamped dynamics
Marc Berneman, Daniel Hexner
In regimes where inertia is negligible, the temporal evolution is governed by overdamped dynamics. This limit is particularly relevant in soft-matter contexts, such as polymers, co…
Equilibrium Propagation for Dissipative Dynamics
Marc Berneman, Daniel Hexner
Computing gradients of a cost function is central to design-based optimization and machine learning algorithms. Equilibrium propagation provides an exact method to compute gradient…
Banding and polarization in driven multistable materials
Sheng Huang, Daniel Hexner
We study a disordered network of bistable bonds subjected to periodic strain. The model is inspired by experiments on crumpled sheets and it features behaviors associated with glas…
Designing precise dynamical steady states in disordered networks
Marc Berneman, Daniel Hexner
Elastic structures can be designed to exhibit precise, complex, and exotic functions. While recent work has focused on the quasistatic limit governed by force balance, the mechanic…
