Thermopower with broken time-reversal symmetry
Keiji Saito, Giuliano Benenti, Giulio Casati +1
We show that when non-unitary noise effects are taken into account the thermopower is in general asymmetric under magnetic field reversal, even for non-interacting systems. Our fin…
Nonequilibrium density matrix description of steady state quantum transport
Abhishek Dhar, Keiji Saito, Peter Hanggi
With this work we investigate the stationary nonequilibrium density matrix of current carrying nonequilibrium steady states of in-between quantum systems that are connected to rese…
Additivity Principle in High-dimensional Deterministic Systems
Keiji Saito, Abhishek Dhar
The additivity principle (AP), conjectured by Bodineau and Derrida [Phys. Rev. Lett. vol.92, 180601 (2004)], is discussed for the case of heat conduction in three-dimensional disor…
Extended Clausius Relation and Entropy for Nonequilibrium Steady States in Heat Conducting Quantum Systems
Keiji Saito, Hal Tasaki
Recently, in their attempt to construct steady state thermodynamics (SST), Komatsu, Nakagwa, Sasa, and Tasaki found an extension of the Clausius relation to nonequilibrium steady s…
Thermodynamic Bounds on Efficiency for Systems with Broken Time-reversal Symmetry
Giuliano Benenti, Keiji Saito, Giulio Casati
We show that for systems with broken time-reversal symmetry the maximum efficiency and the efficiency at maximum power are both determined by two parameters: a "figure of merit" an…
Fluctuation Theorem and Microreversibility in a Quantum Coherent Conductor
Shuji Nakamura, Yoshiaki Yamauchi, Masayuki Hashisaka +8
Mesoscopic systems provide us a unique experimental stage to address non-equilibrium quantum statistical physics. By using a simple tunneling model, we describe the electron exchan…
