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.
