Computation of the Time-Dependent Dirac Equation with Physics-Informed Neural Networks

Emmanuel Lorin, Xu Yang

We propose to compute the time-dependent Dirac equation using physics-informed neural networks (PINNs), a new powerful tool in scientific machine learning avoiding the use of appro…

Numerical quasi-conformal transformations for electron dynamics on strained graphene surfaces

F. Fillion-Gourdeau, E. Lorin, S. MacLean

The dynamics of low energy electrons in general static strained graphene surface is modelled mathematically by the Dirac equation in curved space-time. In Cartesian coordinates, a…

A Split-Step Numerical Method for the Time-Dependent Dirac Equation in 3-D Axisymmetric Geometry

François Fillion-Gourdeau, Emmanuel Lorin, André D. Bandrauk

A numerical method is developed to solve the time-dependent Dirac equation in cylindrical coordinates for 3-D axisymmetric systems. The time evolution is treated by a splitting sch…
