Our student Victor Romero from USACH will give an account of his PhD work. Victor is currently studying divergent tears in different films and substrates that show very robust scaling laws. His findings can have potential applications in the packaging industry since convergent tears lead to the failure of the opening process. The seminar will take place in the laboratory Matter out of Equilibrium (FCFM, downstairs) on Tuesday at 16:00.
Después de un largo intevalo provocado por múltiples razones volvemos a nuestros seminarios de los días martes. El profesor Jorge Lobiano del Departamento de Arquitectura de la Universidad de Santiago dará una charla sobre el uso de materiales ligeros para construir objetos. Este será a las 14:30 hrs en el laboratorio de Materia Fuera del Equilibrio.
Next Tuesday professor Eric Louvergneaux from Université de Lille will give a seminar on pattern formation. Please see below a
summary of the talk. The seminar will take place in the laboratory of
Matter out of Equilibrium (DFI, downstairs) at 16pm.
Title
Spatiotemporal Antiphase Dynamics in Mutually Coupled
Kerr Optical Media
Summary
Experimental evidence of spatiotemporal antiphase dynamics is given for an extended system made of two liquid crystal slices that are optically coupled by two equal amplitude counter-propagating pumping beams. Theory and experiments carried out in a transverse one-dimensional configuration show that roll patterns are generated in each slice. These rolls are spatially in-phase or in antiphase for a focusing or a defocusing nonlinearity type, respectively. These in-/antiphase dynamics remain robust even for complex spatiotemporal regimes such as dislocation regimes.
