Two field BPS solutions for generalized Lorentz breaking models
A. de Souza Dutra, M. Hott, F. A. Barone
In this work we present nonlinear models in two-dimensional space-time of two interacting scalar fields in the Lorentz and CPT violating scenarios. We discuss the soliton solutions…

Quantum propagator for some classes of three-dimensional three-body systems
A. de Souza Dutra
In this work we solve exactly a class of three-body propagators for the most general quadratic interactions in the coordinates, for arbitrary masses and couplings. This is done bot…
