Multifractality of random eigenfunctions and generalization of Jarzynski equality
Abstract
Systems driven out of equilibrium experience large fluctuations of the dissipated work. The same is true for wave function amplitudes in disordered systems close to the Anderson localization transition.\cite{Mirlin-review} In both cases the probability distribution function (PDF) is given by the large deviation ansatz. Here we exploit the analogy between the PDF of work dissipated in a driven single-electron box (SEB) and that of random multifractal wave function amplitudes and uncover new relations which generalize the Jarzynski equality. We checked the new relations experimentally by measuring the dissipated work in a driven SEB and found a remarkable correspondence. The results represent an important universal feature of the work statistics in systems out of equilibrium and help to understand the nature of the symmetry of multifractal exponents in the theory of Anderson localization.
