Las propiedades estadísticas de los sistemas físicos en equilibrio termodinámico quedan completamente y formalmente descritas por la potente Teoría de las Colectividades descubiertas por Boltzmann y desarrolladas posteriormente por Gibbs. Ésta teoría se construye de forma que se cumplan las… Continuar leyendo
Working memory is defined as the ability of the brain to retain and manipulate information over short periods of time. While traditionally associated with persistent neural firing in prefrontal cortex, mounting evidence suggests that neural correlates of working memory can… Continuar leyendo
Existen distintos métodos que permiten crear un pozo de potencial parabólico para el atrapamiento estable de partículas de modo que estas puedan estudiarse en excelentes condiciones de estabilidad y de control del medio. En esta charla, discutiremos algunos experimentos recientes… Continuar leyendo
The contact process is a paradigmatic classical stochastic system displaying critical behaviour even in one dimension. It features a non-equilibrium phase transition into an absorbing state that has been widely investigated and shown to belong to the directed percolation universality… Continuar leyendo
[La fecha del seminario ha sido aplazada del día viernes 8 de marzo al viernes 15 de marzo] The inverse stochastic resonance (ISR) phenomenon consists in an unexpected suppression in the activity of a natural system under the influence of… Continuar leyendo
Quantum transport in lattices is a major field of study nowadays. It has been probed that a lattice composed by harmonic oscillators connected to two thermal baths at different temperatures behaves ballistically in any dimension [1]. On the other hand,… Continuar leyendo
Understanding how evolution works is an open question in ecological systems. In the last years there has been an effort to understand host-parasite systems. Despite the advances in the field of computational epidemiology, there are many features of the observed… Continuar leyendo
Cortical networks are shaped by the combined action of excitatory and inhibitory interactions. We elucidate a general noise-induced effect that we call “Jensen’s force” –stemming from the combined effect of excitation/inhibition balance and network sparsity– which is responsible for generating… Continuar leyendo
In one of his celebrated 1905 papers, Albert Einstein proposed for the first time a statistical interpretation of Robert Brown’s innocent observation based on the corpuscular constitution of matter. His theory stated that the long-time motion of a Brownian particle… Continuar leyendo
The chronological age (CHA) differs from the biological one. While the former is defined as the time running as birth, the latter quantifies the maturity level that an individual (or an organ) has at the operational level. In relation with… Continuar leyendo
