Vacuum Cherenkov radiation for nonminimal dimension-5 Lorentz violation
A. Yu. Petrov, M. Schreck, A. R. Vieira
Vacuum Cherenkov radiation is investigated in the Lorentz-violating Standard-Model Extension for isotropic dim-5 operators and in the fermion sector. Both th…

Dynamical Lorentz Symmetry Breaking in a Scale-free Theory of Gravity
A. C. Lehum, J. R. Nascimento, A. Yu. Petrov +1
This paper explores the renormalization of scale-free quadratic gravity coupled to the bumblebee field and its potential for dynamically breaking Lorentz symmetry. We conduct one-l…
