Mobility properties of spatially localized structures arising from chaotic but deterministic forcing of the bistable Swift-Hohenberg equation are studied and compared with the corresponding results when the chaotic forcing is replaced by white noise. Short structures are shown to possess greater mobility, resulting in larger root-mean-square speeds but shorter displacements than longer structures. Averaged over…

Digital Transformation with GCP Badge
I will retake the posting on this blog recommending the course: Introduction to Digital Transformation with Google Cloud. https://googlecourses.qwiklabs.com/course_templates/266 It is an interest course with focus on understand the value offer of the public cloud services and how to take advantage of it in the path to the digital transformation.
Paper: Transition from nonradiative to radiative oscillons in parametrically driven systems
Nonequilibrium systems exhibit particle-type solutions. Oscillons are one of the best-known localized states of systems with time-dependent forcing or parametrically driven systems. We investigate the transition from nonradiative to radiative oscillons in the parametrically driven sine-Gordon model in two spatial dimensions. The bifurcation takes place when the strength of the forcing (frequency) increases (decreases) above…

A webinar about the COVID, technological tools for monitor COVID-19, and mathematical models for predicts its propagation.
Paper: Front depinning by deterministic and stochastic fluctuations: A comparison
Driven dissipative many-body systems are described by differential equations for macroscopic variables which include fluctuations that account for ignored microscopic variables. Here, we investigate the effect of deterministic fluctuations, drawn from a system in a state of phase turbulence, on front dynamics. We show that despite these fluctuations a front may remain pinned, in contrast…
Paper: Front propagation transition induced by diffraction in a liquid crystal light valve
Driven optical systems can exhibit coexistence of equilibrium states. Traveling waves or fronts between different states present complex spatiotemporal dynamics. We investigate the mechanisms that govern the front spread. Based on a liquid crystal light valve experiment with optical feedback, we show that the front propagation does not pursue minimization of free energy. Depending on…
Internship at the University of A Coruña
I realize a second internship at the Universidad de A Coruña in Spain, under the direction of the professors Susana Ladra and Oscar Pedreira, focused on the design and implementation of algorithms for data processing/mining. During my stay here I start a research project, that maybe will be finished soon. In addition, I appear in…
My internship at the Université Libre de Bruxelles (ULB)
In the first months of this year, I realize an internship in the Physics department at the Université Libre de Bruxelles (ULB). This was a fantastic experience for me as a Ph.D. student, thanks to the professor Mustapha Tlidi and my advisor Marcel Clerc, I get a lot of experience in my field (nonlinear physics…
