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…

Aspects of wave turbulence in preheating II: Rebirth of the nonminimal coupled models
J. A. Crespo, H. P. de Oliveira
We study the nonlinear stage of preheating in a model consisting of a single inflaton field nonminimally coupled to the spacetime curvature and considering a self-coupling quar…
