Efficient asymmetric collisional Brownian particle engines
C. E. Fernández Noa, Angel L. L. Stable, William G. C. Oropesa +2
The construction of efficient thermal engines operating at finite times constitutes a fundamental and timely topic in nonequilibrium thermodynamics. We introduce a strategy for opt…
Maximal power for heat engines: role of asymmetric interaction times
Pedro E. Harunari, Fernando S. Filho, Carlos E. Fiore +1
The performance of endoreversible thermal machines operating at finite power constitutes one of the main challenges of nonequilibrium classical and quantum thermodynamics, engineer…
Stochastic thermodynamics for a periodically driven single-particle pump
Alexandre Rosas, Christian Van den Broeck, Katja Lindenberg
We present the stochastic thermodynamic analysis of a time-periodic single particle pump, including explicit results for flux, thermodynamic force, entropy production, work, heat a…
Energy Transport in a One-Dimensional Granular Gas
Italo Ivo Lima Dias Pinto, Alexandre Rosas, Katja Lindenberg
We study heat conduction in one-dimensional granular gases. In particular, we consider two mechanisms of viscous dissipation during inter-grain collisions. In one, the dissipative…
Velocity Distribution in a Viscous Granular Gas
Alexandre Rosas, Daniel ben-Avraham, Katja Lindenberg
We investigate the velocity relaxation of a viscous one-dimensional granular gas, that is, one in which neither energy nor momentum is conserved in a collision. Of interest is the…
Pulse Velocity in a Granular Chain
Alexandre Rosas, Katja Lindenberg
We discuss the applicability of two very different analytic approaches to the study of pulse propagation in a chain of particles interacting via a Hertz potential, namely, a contin…
Self-Similarity in Random Collision Processes
Daniel ben-Avraham, Eli Ben-Naim, Katja Lindenberg +1
Kinetics of collision processes with linear mixing rules are investigated analytically. The velocity distribution becomes self-similar in the long time limit and the similarity fun…
Pulse Dynamics in a Chain of Granules With Friction
Alexandre Rosas, Katja Lindenberg
We study the dynamics of a pulse in a chain of granules with friction. We present theories for chains of cylindrical granules (Hertz potential with exponent ) and of granules…
Dynamics of Two Granules
Alexandre Rosas, J. Buceta, Katja Lindenberg
We study the dynamics of two particles that interact only when in contact. In this sense, although not in every particular, the interactions mimic those in granular materials. The…
Multifractal analysis of DNA walks and trails
Alexandre Rosas, Edvaldo Nogueira, José F. Fontanari
The characterization of the long-range order and fractal properties of DNA sequences has proved a difficult though highly rewarding task due mainly to the mosaic character of DNA c…
