Línies d'Investigació

Descripció

Els Sistemes Complexos, un paradigma central a l’IFISC, es caracteritzen pels fenòmens emergents i col·lectius de molts elements en interacció. Una comprensió bàsica d’aquest sistemes arriba des de la Física Estadística, junt amb la Teoria dels Sistemes Dinàmics, incloent-hi l’estudi del caos i l’efecte de fluctuacions i fenòmens aleatoris. Fenòmens genèrics en estudi inclouen sincronització, transicions de fase, inestabilitats de no equilibri, formació d’estructures espacio-temporals, o la dinàmica i evolució de xarxes complexes.
