Descrizione del progetto DEENESFRITPL Testare il comportamento collettivo degli agenti attivi usando la luce La materia attiva comprende sistemi i cui costituenti fondamentali dissipano energia per esercitare forze reciproche. Dai motori molecolari alle colonie batteriche, ai banchi di pesci e alle folle umane, gli agenti attivi si trovano a tutte le scale della natura. Tali sistemi sono intrinsecamente estranei all’equilibrio termico. Gli agenti eccitati internamente rappresentano meglio la materia attiva rispetto a quelli eccitati da forze esterne, ma non esiste ancora un modo per verificare la loro risposta agli stimoli esterni. Il progetto PhotoActive, finanziato dal programma di azioni Marie Skłodowska-Curie, si propone di progettare agenti macroscopici semoventi, eccitati internamente ma guidati da uno stimolo esterno. L’idea è quella di sviluppare e implementare particelle simili a Hexbug, la cui fonte di energia proviene da una cella fotovoltaica. Mostra l’obiettivo del progetto Nascondi l’obiettivo del progetto Obiettivo In the last years, there has been an outstanding growing interest in active matter. In these complex systems, a number of interacting agents consume and convert energy into mechanical motion, representing nice examples of out-of-equilibrium behavior. Such systems are important because they can be found in nature ranging from the microscopic to the macroscopic scale, e.g. molecular motors, cells, bird flocks, or human crowds. Interestingly, and despite the obvious differences among the agents that compose these systems, common behavioral patterns have been identified such as collective motion, anomalous diffusion, segregation, or clogging in the flow through constrictions. Aiming for a better understanding of these complex active systems a reductionist strategy is necessary, and this is why the study of active granular matter (very simple self-propelled agents that interact uniquely by contacts) is widely acknowledged. Within active grains, we can distinguish between internally excited ones (such as Hexbugs) or externally forced ones. Certainly, the former have the advantage to closely resemble real active matter but, to date, also have the drawback of not allowing testing their response to external stimulus. My proposal, PhotoActive, aims to fill this gap by designing novel macroscopic self-propelled agents that are internally excited but can be driven by an external stimulus as it occurs with all natural systems. The idea is to develop and implement Hexbug-like particles whose source of energy comes from a photovoltaic cell. The great advantage of these novel agents concerns the versatility that provides using a fully controllable illumination panel with which we can impose spatial intensity gradients or temporally evolving patterns. In this way, and applying an interdisciplinary approach involving experiments, numerical modeling, and simulations, we ambition boosting the existing understanding of active matter systems.
