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…

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…

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…
