Bona-Masso slicing conditions and the lapse close to black-hole punctures
Thomas W. Baumgarte, Henrique P. de Oliveira
We consider several families of functions that appear in the Bona-Masso slicing condition for the lapse function . Focusing on spherically symmetric and time-independent…
The affine-null formulation of the gravitational equations: spherical case
J. A. Crespo, H. P. de Oliveira, J. Winicour
A new evolution algorithm for the characteristic initial value problem based upon an affine parameter rather than the areal radial coordinate used in the Bondi-Sachs formulation is…
Aspects of wave turbulence in preheating III: The case of the two-fields models
J. A. Crespo, H. P. de Oliveira
The present work is the continuation of the investigation of aspects of wave turbulence in preheating we have started in Refs. [1, 2] but considering several classes of inflationar…
The collision of two-kinks revisited: the creation of kinks and lump-like defects as metastable states
T. S. Mendonça, H. P. de Oliveira
We present a more detailed numerical investigation of the head-on collision of a two-kink/two-antikink system. We identified the escape of oscillon-like configurations as a pair of…
