Research topics

LR works in statistical physics, particularly on the subject of fluctuations at the nanoscale and of general non-equilibrium systems. Statistical mechanics aims at describing the physical properties of a macroscopic system on the basis of the behaviour of its microscopic constituents [1]. The most developed part of statistical physics concerns equilibrium situations, but the majority of assumptions employed for systems at equilibrium has very limited application for out of equilibrium phenomena. Recent efforts led by a number of scientists including LR have unveiled exciting new and rigorous results, which are collectively known as Fluctuation Relations [2-5]. These represent one of the few general, accurate descriptions achieved so far in non-equilibrium systems, covering a wide variety of phenomena and observables; moreover these developments led to numerous results concerning the response of a most wide class of systems to perturbations. Currently, research in this field is of particular interest in bio- and nano-sciences and technology, as well as in "soft" sciences (socio-economic, media and communications etc.) in which the notion of proper equilibrium cannot be established, and stationary states are characterized by large fluctuations.
