Absorbing boundary conditions for relativistic quantum mechanics equations
نویسندگان
چکیده
This paper is devoted to the derivation of absorbing boundary conditions for the KleinGordon and Dirac equations modeling quantum and relativistic particles subject to classical electromagnetic fields. Microlocal analysis is the main ingredient in the derivation of these boundary conditions, which are obtained in the form of pseudodifferential equations. Basic numerical schemes are derived and analyzed to illustrate the accuracy of the derived boundary conditions. Keyword words: Microlocal analysis, pseudo-differential operators, absorbing boundary conditions, wave equation, Dirac equation, Klein-Gordon equation, numerical approximation.

Absorbing layers for the Dirac equation
This work is devoted to the construction of perfectly matched layers (PML) for the Dirac equation, that not only arises in relativistic quantum mechanics but also in the dynamics of electrons in graphene or in topological insulators. While the resulting equations are stable at the continuous level, some care is necessary in order to obtain a stable scheme at the discrete level. This is related ...

متن کاملAbsorbing boundary conditions for solving stationary Schrödinger equations
Using pseudodifferential calculus and factorization theorems we construct a hierarchy of novel absorbing boundary conditions (ABCs) for the stationary Schrödinger equation with general (linear and nonlinear) exterior potential V (x). Doing so, we generalize the well-known quantum transmitting boundary condition of Lent and Kirkner to the case of space-dependent potential. Here, we present a bri...
متن کاملImplementation of Absorbing Boundary Conditions for the Einstein Equations
Based on a recent study of the linearized Bianchi equations by Buchman and Sarbach, we construct and implement a hierarchy of absorbing boundary conditions for the Einstein equations in generalized harmonic gauge. As a test problem, we demonstrate that we can evolve multipolar gravitational waves without any spurious reflections at linear order in perturbation theory.
متن کاملRelativistic spin-density-functional theory: Robust solution of single-particle equations for open-subshell atoms
We present an approach to the solution of the collinear form of the single-particle equations of relativistic spin-density-functional theory. It is based on the use of appropriate boundary conditions for r→0,` and the identification of ‘‘spin-up’’ and ‘‘spin-down’’ solutions by a node quantum number. A comparison with previous results and a complete set of reference data for atomic ground state...
