Abstract
An experimental test of a large fluctuation theorem is performed on a chain of coupled ``cat maps''. Our interest is focused on the behavior of a subsystem of this chain. A {\it local} entropy creation rate is defined and we show that the local fluctuation theorem derived in \cite{Ga1} is experimentally observable already for small subsystems, \ie the finite size effects, for which the theory says little, are small even in small subsystems of the systems considered.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
