Driven diffusive systems may undergo phase transitions to sustain atypical values of the current. This leads in some cases to symmetry-broken space-time trajectories which enhance the probability of such fluctuations. In this talk I will shed light on both the macroscopic… Continuar leyendo
Recent experiments with a rotating probe immersed in weakly fuidized granular materials show a complex behavior on a wide range of timescales [1]. Viscous-like relaxation at high frequency is accompanied by an almost harmonic dynamical trap- ping at intermediate times,… Continuar leyendo
Self-organized criticality elucidates the conditions under which physical and biological systems tune themselves to the edge of a second-order phase transition, with scale invariance. Motivated by the empirical observation of bimodal distributions of activity in neuroscience and other fields, we… Continuar leyendo
Symmetry is a key concept in quantum mechanics and it plays an important role in many systems found in Nature, including many biological systems as photosynthetic complexes. Recently, the implications of symmetries in the thermodynamics of currents in open quantum… Continuar leyendo
Las películas magnéticas delgadas presentan una variedad de patrones a escala mesoscópica, los cuales pueden se controlados mediante parámetros extrínsecos como la temperatura y el campo magnético o intrínsecos como su espesor, las interacciones entre capas atómicas y las propiedades… Continuar leyendo
Interactions between visual cortical areas occur in both feedforward and feedback directions along the visual hierarchy, with feedforward interactions carrying signals from sensory areas to higher areas and feedback interactions conveying top-down signals which modulate perception. Several recent works have… Continuar leyendo
A dense gas of atoms where the average interatomic distance is smaller than the wavelength of the photons emitted from the atoms exhibits strong dipolar interactions and collective dissipation. I will discuss the underlying many-body master equation, investigate the dynamics… Continuar leyendo
Evolutionary and ecosystem dynamics are often treated as different processes, operating at separate timescales. However, empirical evidence reveals that rapid evolutionary changes in complex communities can feedback into ecological interactions; e.g. recent work shows that competing plant species can experience… Continuar leyendo
