Nonlinear optical thermodynamics from a van der Waals-type mean-field theory
Meng Lian, Zhongfei Xiong, Yuntian Chen +1
Optical thermodynamics offers a distinctive framework for understanding complex phenomena in multimode systems, yet standard ideal-gas-like formulation neglects the effect of nonli…
Kinetic simulation of magnetic-field-tuned hydrodynamic electron transport in graphene corbino disk
Chuang Zhang, Meng Lian, Hong Liang +3
Hydrodynamic electron transport, in which electrical transport in solids resembles fluid hydrodynamics when momentum-conserving electron-electron scattering dominates, has attracte…
Semi-implicit Lax-Wendroff kinetic scheme for electron-phonon coupling
Jiaming Li, Hong Liang, Meng Lian +2
A semi-implicit Lax-Wendroff scheme is developed for electron-phonon coupling process in metals based on the two-temperature kinetic equations. The core of this method is to integr…
Non-equilibrium transport and phonon branch-resolved size effects based on a multi-temperature kinetic model
Chuang Zhang, Houssem Rezgui, Meng Lian +1
Non-equilibrium transport and phonon branch-resolved size effects in single-layer graphene materials are studied under a multi-temperature kinetic model, which is developed for cap…
Discrete unified gas kinetic scheme for the solution of electron Boltzmann transport equation with Callaway approximation
Meng Lian, Chuang Zhang, Zhaoli Guo +1
Electrons are the carriers of heat and electricity in materials, and exhibit abundant transport phenomena such as ballistic, diffusive, and hydrodynamic behaviors in systems with d…
