Heat flux operator, current conservation and the formal Fourier's law
Lian-Ao Wu, Dvira Segal
By revisiting previous definitions of the heat current operator, we show that one can define a heat current operator that satisfies the continuity equation for a general Hamiltonia…
Thermal conduction in molecular chains: Non-Markovian effects
Dvira Segal
We study the effect of non-Markovian reservoirs on the heat conduction properties of short to intermediate size molecular chains. Using classical molecular dynamics simulations, we…
Single mode heat rectifier: Controlling energy flow between electronic conductors
Dvira Segal
We study heat transfer between conductors, mediated by the excitation of a monomodal harmonic oscillator. Using a simple model, we show that the onset of rectification in the syste…
Thermoelectric effect in molecular junctions: A tool for revealing transport mechanisms
Dvira Segal
We investigate the thermopower of a metal-molecule-metal junction taking into account thermal effects on the junction. Based on analytical expressions and numerical simulations we…
Molecular heat pump
Dvira Segal, Abraham Nitzan
We propose a novel molecular device that pumps heat against a thermal gradient. The system consists of a molecular element connecting two thermal reservoirs that are characterized…
A spin-boson thermal rectifier
Dvira Segal, Abraham Nitzan
Rectification of heat transfer in nanodevices can be realized by combining the system inherent anharmonicity with structural asymmetry. we analyze this phenomenon within the simple…
