Realistic prediction and analysis of cavitation bubble dynamics via optical ray-tracing of the corresponding numerical simulations
Max Koch, Juan Manuel Rosselló, Christiane Lechner +3
Experimental analysis of cavitation bubble dynamics typically uses optical imaging. However, images are often severely affected by distortions and shadows due to refraction and tot…
Jet formation from bubbles near a solid boundary in a compressible liquid. Numerical study of distance dependence
Christiane Lechner, Werner Lauterborn, Max Koch +1
A small, spherical bubble of high internal pressure is inserted into water at constant ambient pressure as a model of a laser-induced bubble. Its subsequent dynamics near a flat so…
Staticity, Self-Similarity and Critical Phenomena in a Self-Gravitating Nonlinear Sigma Model
Christiane Lechner
The main part of the thesis deals with continuously and discretely self-similar solutions and type II critical phenomena in a family of self-gravitating non-linear sigma-models. Th…
The spin-dependent semiconductor Bloch equations: a microscopic theory of Bir-Aronov-Pikus spin-relaxation
C. Lechner, U. Roessler
Semiconductor Bloch equations, in their extension including the spin degree of freedom of the carriers, are capable to describe spin dynamics on a microscopic level. In the presenc…
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…
