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…
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…
Distributional Ergodicity in Stored-Energy-Driven Lévy Flights
Takuma Akimoto, Tomoshige Miyaguchi
We study a class of random walk, the stored-energy-driven Lévy flight (SEDLF), whose jump length is determined by a stored energy during a trapped state. The SEDLF is a continuous-…
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…
