Simulation of the effect of short optical pulses on graphene
The interaction of high-frequency pulsed electric
fields with graphene is currently the subject of intense research.
The paper presents the results of testing a software system for
modeling such processes using the example of ultrashort laser pulses
of the optical range with different polarizations. The authors
develop the system on a base of a new theoretical approach based on
the quantum kinetic equation. The approach contains a computational
model for a new system of ordinary differential equations with
non-linearly dependent on time and problem parameters coefficients.
The need to analyze the behavior of solutions of this system of
equations in the field of changing several parameters leads to the
polynomial computational complexity. The lack of knowledge of the
nature of the parametric dependence of solutions requires several
iterations of the choice of covering grids. The paper describes the
adaptation of this modeling system for use in massively parallel
computing systems. (In Russian).
Key words: numerical simulation, high performance
computing, graphene, kinetic equation. |
