Degenerate optimal paths in thermally isolated systems.
We present an analysis of the work performed on a system of interest that is kept thermally isolated during the switching of a control parameter. We show that there exists, for a certain class of systems, a finite-time family of switching protocols for which the work is equal to the quasistatic value. These optimal paths are obtained within linear response for systems initially prepared in a ca...
متن کاملComment on "Universal Fluctuations in Correlated Systems".
1 In [1], it is suggested that the probability distribution functions (PDF's) of fluctuating observables for critical systems in different universality classes exhibit a same form. This Comment concerns the PDF's for equilibrium systems. In [2], it is pointed out that the standard scaling form is a sufficient condition for the data collapse. The suggestion in [1] seems contradicting the idea of...
متن کاملUniversal impedance fluctuations in wave chaotic systems.
We experimentally investigate theoretical predictions of universal impedance fluctuations in wave chaotic systems using a microwave analog of a quantum chaotic infinite square well potential. We emphasize the use of the radiation impedance to remove the nonuniversal effects of the particular coupling between the outside world and the scatterer. Specific predictions that we test include the prob...
متن کاملUniversal triangular spectra in parametrically-driven systems
Article history: Received 12 November 2010 Accepted 16 November 2010 Available online 20 November 2010 Communicated by V.M. Agranovich We analyse triangular spectra that appear in many branches of physics that deal with parametricallydriven systems, and give a simple theoretical analysis for them in terms of the nonlinear dynamics of multimode fields. Such spectra appear universally as a result...
متن کاملEntropy Production in Nonlinear, Thermally Driven Hamiltonian Systems
We consider a finite chain of nonlinear oscillators coupled at its ends to two infinite heat baths which are at different temperatures. Using our earlier results about the existence of a stationary state, we show rigorously that for arbitrary temperature differences and arbitrary couplings, such a system has a unique stationary state. (This extends our earlier results for small temperature diff...
