WebbA numerical scheme utilizing a grid which is staggered in both space and time is proposed for the numerical solution of the (2 + 1) D Dirac equation in the presence of an external electromagnetic potential. It preserves the linear dispersion relation of the free Weyl equation for wave vectors aligned with the grid and facilitates the implementation of … WebbTherefore, to reveal the behaviors of heat transport in the system, we will numerically solve the steady state of the master equation (15) as well as the steady-state heat currents. At first, we mainly take two coupling regimes as examples, one is the strong coupling with g = 0.015 ω 0 , and the other is the ultrastrong coupling with g = 0.45 ω 0 .
