An efficient thermal diode with ballistic spacer
Shunda Chen, Davide Donadio, Giuliano Benenti +1
Thermal rectification is of importance not only for fundamental physics, but also for potential applications in thermal manipulations and thermal management. However, thermal recti…
Key role of asymmetric interactions in low-dimensional heat transport
Shunda Chen, Yong Zhang, Jiao Wang +1
We study the heat current autocorrelation function (HCAF) in one-dimensional, momentum-conserving lattices. In particular, we explore if there is any relation between the decaying…
Connection between heat diffusion and heat conduction in one-dimensional systems
Shunda Chen, Yong Zhang, Jiao Wang +1
Heat and energy are conceptually different, but often are assumed to be the same without justification. An effective method for investigating diffusion properties in equilibrium sy…
Ingredients for an efficient thermal diode
Shunda Chen, Emmanuel Pereira, Giulio Casati
We provide convincing empirical evidence that long range interactions strongly enhance the rectification effect which takes place in mass graded systems. Even more importantly the…
Thermoelectricity of interacting particles: A numerical approach
Shunda Chen, Jiao Wang, Giulio Casati +1
A method for computing the thermopower in interacting systems is proposed. This approach, which relies on Monte Carlo simulations, is illustrated first for a diatomic chain of hard…
Non-integrability and the Fourier heat conduction law
Shunda Chen, Jiao Wang, Giulio Casati +1
We study in momentum-conserving systems, how nonintegrable dynamics may affect thermal transport properties. As illustrating examples, two one-dimensional (1D) diatomic chains, rep…
Why asymmetric interparticle interaction can result in convergent heat conductivity
Shunda Chen, Yong Zhang, Jiao Wang +1
We show that the asymmetric inter-particle interactions may induce rapid decay of heat current autocorrelation in one-dimensional momentum conserving lattices. When the asymmetry d…
Breakdown of effective phonon theory in one-dimensional chains with asymmetric interactions
Yong Zhang, Shunda Chen, Jiao Wang +1
Phonons are universal language for solid state theory. Effective phonon theory (self-consistent harmonic approximation) have been extensively used to access the weakly nonlinear ef…
Finite-size effects on current correlation functions
Shunda Chen, Yong Zhang, Jiao Wang +1
We study why the calculation of current correlation functions (CCFs) still suffers from finite size effects even when the periodic boundary condition is taken. Two important one di…
Breakdown of the power-law decay prediction of the heat current correlation in one-dimensional momentum conserving lattices
Shunda Chen, Yong Zhang, Jiao Wang +1
We show that the asymmetric inter-particle interactions can induce rapid decay of the heat current correlation in one-dimensional momentum conserving lattices. When the asymmetry d…
Diffusion of heat, energy, momentum, and mass in one-dimensional systems
Shunda Chen, Yong Zhang, Jiao Wang +1
We study diffusion processes of local fluctuations of heat, energy, momentum, and mass in three paradigmatic one-dimensional systems. For each system, diffusion processes of four p…
