2D Ising-Heisenberg model with quartic interaction

Valverde, J.S. (Вопросы атомной науки и техники, 2012)

We propose a two-dimensional spin-1/2 Ising-Heisenberg model with quartic interaction. In this sense the phase diagram for the model at zero temperature is studied, obtaining four different configurations for the unitary ...
The causal approach to scalar QED via Duffin-Kemmer-Petiau equation

Lunardi, J.T.; Manzoni, L.A.; Pimentel, B.M.; Valverde, J.S. (Вопросы атомной науки и техники, 2001)

In this work we consider the scalar QED via Duffin-Kemmer-Petiau equation in the framework of Bogoliubov-Epstein-Glaser causal perturbation theory. We calculate the lowest order distributions for Compton scattering, vacuum ...
