Evolving a puncture black hole with fixed mesh refinement
Breno Imbiriba, John Baker, Dae-Il Choi +5
We present an algorithm for treating mesh refinement interfaces in numerical relativity. We detail the behavior of the solution near such interfaces located in the strong field reg…

Interface Conditions for Wave Propagation Through Mesh Refinement Boundaries
Dae-Il Choi, J. David Brown, Breno Imbiriba +2
We study the propagation of waves across fixed mesh refinement boundaries in linear and nonlinear model equations in 1--D and 2--D, and in the 3--D Einstein equations of general re…

Exploring the Supersymmetric Sigma Model
Breno C. O. Imbiriba
The purpose of this work is to present some basic concepts about the non-linear sigma model in a simple and direct way. We start with showing the bosonic model and the Wess-Zumino-…
