Highly-efficient noise-assisted energy transport in classical oscillator systems

Photosynthesis is a biological process that involves the highly-efficient transport of energy captured from the sun to a reaction center, where conversion into useful biochemical energy takes place. Even though one can always use a quantum perspective to describe any physical process, since everything follows the laws of Quantum Mechanics, is the use of quantum theory imperative to explain this high efficiency? Making use of the quantum-classical correspondence of electronic energy transfer recently introduced by Eisfeld and Briggs [Phys. Rev. E 85, 046118 (2012)], we show here that the highly-efficient noise-assisted energy transport described by Rebentrost et al. [New J. Phys. 11, 033003 (2009)], and Plenio and Huelga [New J. Phys. 10, 113019 (2008)], as the result of the interplay between the quantum coherent evolution of the photosynthetic system and noise introduced by its surrounding environment, it can be found as well in purely classical systems. The wider scope of applicability of the enhancement of energy transfer assisted by noise might open new ways for developing new technologies aimed at enhancing the efficiency of a myriad of energy transfer systems, from information channels in micro-electronic circuits to long-distance high-voltage electrical lines.Comment: 4 pages, 3 figure

El tema del placer en Platón

The author sees an evolution of the theory of pleasure in different dialogues of Plato. Martos is aware of the contradictions of this theory in the course of Plato's philosophical development and he says that Aristotle tried to reconcile these contradictions

Un nuevo hápax en Vetio Valente: γυναικοκαυσία

Frente a la conjetura γυναῖκες Καυνίαι de D. Pingree en Vett. Val., II 37,17, se defiende con matices el mantenimiento por parte de W. Kroll de la lección manuscrita, γυναικοκαυσίαι, y se reivindica la inclusión de este hápax en los grandes diccionarios de referencia.Universidad de Málaga.
