New partnership between CNRS and The University of Auckland. The WALL-IN project (confining walls-of-Light in nonlinear Kerr resonators) is a 5-years international research action between the CNRS and The University of Auckland funded by the CNRS and focused on the study of nonlinear dynamics occurring in optical Kerr resonators. The aim is to fund some short and long stays in both Universities for researchers and students. In this framework, Julien will stay in Auckland until next August 2021.
