In the recently published paper in the journal Europhysics Letters, entitled "CP(N−1) model in aether-superspace", we discuss the dynamical generation of mass in the Lorentz-violating CP(N−1) model defined in two- and three-dimensional aether-superspace. We show that even though the model presents a phase structure similar to the usual Lorentz-invariant case, the mass dynamically generated by quantum corrections has a dependence on the Lorentz-violating background properties, except for space-like LV vector parameter. This is to be contrasted with the behavior of the quantum electrodynamics in the two-dimensional aether-superspace, where the dynamical generation of mass was shown to exhibit an explicit dependence on the aether parameters in every possible case. This paper was made in collaboration with Prof. Dr. Alysson Ferrari (UFABC).
