Gravity-Induced Thermal Rectification in Gaseous Systems
Rongxiang Luo, Chao Yang, Juncheng Guo +1
Thermal rectification (TR) typically relies on structural asymmetry or material heterogeneity. Here, we show that gravity alone can induce and modulate TR in gaseous systems. Using…
Heat Conduction in Momentum-Conserving Fluids: From quasi-2D to 3D systems
Rongxiang Luo, Jiaqi Wen, Juncheng Guo
Using nonequilibrium and equilibrium molecular dynamics simulations, we investigate heat conduction in a momentum-conserving mesoscopic fluid modeled by multiparticle collision dyn…
Gravity-Induced Modulation of Negative Differential Thermal Resistance in Fluids
Qiyuan Zhang, Juncheng Guo, Juchang Zou +1
We investigate how gravity influences negative differential thermal resistance (NDTR) in fluids modeled by multiparticle collision dynamics. In the integrable case, we derive the h…
Multi-particle-collision simulation of heat transfer in low-dimensional fluids
Rongxiang Luo, Stefano Lepri
Simulation of transport properties of confined, low-dimensional fluids can be performed efficiently by means of Multi-Particle Collision (MPC) dynamics with suitable thermal-wall b…
Heat conduction in low-dimensional electron gases without and with a magnetic field
Rongxiang Luo, Qiyuan Zhang, Guanming Lin +1
We investigate the behavior of heat conduction in two-dimensional (2D) electron gases without and with a magnetic field. We perform simulations with the Multi-Particle-Collision ap…
Negative differential thermal resistance of fluids induced by heat baths
Rongxiang Luo, Juncheng Guo, Jun Zhang +1
It has recently been shown that in one-dimensional hard-point gases, there is a mechanism that induces negative differential thermal resistance (NDTR) between heat baths. We examin…
Heat conduction in a three-dimensional momentum-conserving fluid
Rongxiang Luo, Lisheng Huang, Stefano Lepri
Size-dependence of energy transport and the effects of reduced dimensionality on transport coefficients are of key importance for understanding nonequilibrium properties of matter…
Onsager symmetry for systems with broken time-reversal symmetry
Rongxiang Luo, Giuliano Benenti, Giulio Casati +1
We provide numerical evidence that the Onsager symmetry remains valid for systems subject to a spatially dependent magnetic field, in spite of the broken time-reversal symmetry. In…
Thermodynamic bound on heat to power conversion
Rongxiang Luo, Giuliano Benenti, Giulio Casati +1
In systems described by the scattering theory, there is an upper bound, lower than Carnot, on the efficiency of steady-state heat to work conversion at a given output power. We sho…
