Thermodynamics and Steady State of Quantum Motors and Pumps Far from Equilibrium
(MDPI, 2019-08-23)
In this article, we briefly review the dynamical and thermodynamical aspects of different forms of quantum motors and quantum pumps. We then extend previous results to provide new theoretical tools for a systematic study ...
Effects of chaotic dynamics on quantum friction
(American Physical Society, 2019-04-22)
By means of studying the evolution equation for the Wigner distributions of quantum dissipative systems we derive the quantum corrections to the classical Liouville dynamics, taking into account the standard quantum friction ...
Dynamics of the electron transport in a quantum wire coupled to a quantum-dot
(ELSEVIER SCIENCE B.V., 2003)
Decoherent time-dependent transport beyond the Landauer-Büttiker formulation: A quantum-drift alternative to quantum jumps
(American Physical Society, 2015-02)
We develop and implement a model for decoherence in time-dependent transport. Inspired in a dynamical formulation of the Landauer-Büttiker equations, it boils down into a form of wave function that undergoes a smooth ...
Periodic Energy Transport and Entropy Production in Quantum Electronics
(Molecular Diversity Preservation International, 2016-11)
The problem of time-dependent particle transport in quantum conductors is nowadays a well established topic. In contrast, the way in which energy and heat flow in mesoscopic systems subjected to dynamical drivings is a ...
DC voltage profile of a 1D pumped wire with two dynamical and one static impurities
(Elsevier Science, 2009-10)
In this work we study the behavior of the voltage profile of a 1D quantum wire with an impurity when transport is induced by two ac voltages that oscillating with a phase lag define a quantum pump. The voltage profile ...
Dynamics of energy transport and entropy production in ac-driven quantum electron systems
(American Physical Society, 2016-07)
We analyze the time-resolved energy transport and the entropy production in ac-driven quantum coherent electron systems coupled to multiple reservoirs at finite temperature. At slow driving, we formulate the first and ...
Sparse 1D discrete Dirac operators I: Quantum transport
(Academic Press Inc. Elsevier B.V., 2012-01-15)
Some dynamical lower bounds for one-dimensional discrete Dirac operators with different classes of sparse potentials are presented, and the particular role of the particle mass is emphasized. (C) 2011 Elsevier B.V. All ...

Nanomagnet coupled to quantum spin Hall edge: An adiabatic quantum motor
(Elsevier Science, 2015-11)
The precessing magnetization of a magnetic islands coupled to a quantum spin Hall edge pumps charge along the edge. Conversely, a bias voltage applied to the edge makes the magnetization precess. We point out that this ...
