Fundamental aspects of steady state heat to work conversion
Giuliano Benenti, Giulio Casati, Tomaz Prosen +1
We review theoretical approaches to analyzing efficiency of steady state heat to work conversion which is crucial in the timely problem of optimizing efficiency of small-scale heat…
A Classical Nernst Engine
Julian Stark, Kay Brandner, Keiji Saito +1
We introduce a simple model for an engine based on the Nernst effect. In the presence of a magnetic field, a vertical heat current can drive a horizontal particle current against a…
Anomalous transport and current fluctuations in a model of diffusing Levy walkers
Abhishek Dhar, Keiji Saito
A Levy walk is a non-Markovian stochastic process in which the elementary steps of the walker consist of motion with constant speed in randomly chosen directions and for a random p…
Kondo signature in heat transfer via a local two-state system
Keiji Saito, Takeo Kato
We study the Kondo effect in heat transport via a local two-state system. This system is described by the spin-boson Hamiltonian with Ohmic dissipation, which can be mapped onto th…
Strong bounds on Onsager coefficients and efficiency for three terminal thermoelectric transport in a magnetic field
Kay Brandner, Keiji Saito, Udo Seifert
For thermoelectric transport in the presence of a magnetic field that breaks time-reversal symmetry, a strong bound on the Onsager coefficients is derived within a general set-up u…
