The emergence of hydrodynamic electronics can be seen in non-local, superballistic and turbulent transport of energy and electric charge. There is a growing interest in the hydrodynamic effects in interacting electron systems in ultra-pure materials. The EU-funded HYDROTRONICS project will build a framework to describe hydrodynamic charge and energy transport fine-tuned to the material properties and sample geometry. It will also investigate the physics of novel materials that can be uncovered by transport measurements. One of the project's goals is for early-stage researchers to develop the path to resolve the biggest issues in the field. A second goal is to promote progress by fostering closer integration between experimental, theoretical and computational parts of the network.
