A microscopic approach to spin dynamics: about the meaning of spin relaxation times
C. Lechner, U. Roessler
We present an approach to spin dynamics by extending the optical Bloch equations for the driven two-level system to derive microscopic expressions for the transverse and longitudin…
From Tensor Equations to Numerical Code -- Computer Algebra Tools for Numerical Relativity
Christiane Lechner, Dana Alic, Sascha Husa
In this paper we present our recent work in developing a computer-algebra tool for systems of partial differential equations (PDEs), termed "Kranc". Our work is motivated by the pr…
An extension of the optical Bloch equations: a microscopic approach including spin and carrier-phonon scattering
C. Lechner, U. Roessler
This paper has been withdrawn by the authors. This is due to the fact that it has been substantially revised. As a consequence title and aim of the contents
Kranc: a Mathematica application to generate numerical codes for tensorial evolution equations
Sascha Husa, Ian Hinder, Christiane Lechner
We present a suite of Mathematica-based computer-algebra packages, termed "Kranc", which comprise a toolbox to convert (tensorial) systems of partial differential evolution equatio…
