Effects of Lorentz violation in the Bose-Einstein condensation
J. Furtado, A. C. A. Ramos, J. F. Assunção
In this paper we study the corrections emergent from a Lorentz-violating CPT-odd extension of the complex scalar sector to the Bose-Einstein condensation and to the thermodynamics…
Dynamical Lorentz symmetry breaking in a tensor bumblebee model
J. F. Assunção, T. Mariz, J. R. Nascimento +1
In this paper, we formulate a theory of the second-rank antisymmetric (pseudo)tensor field minimally coupled to a spinor, calculate the one-loop effective potential of the (pseudo)…
Induced Chern-Simons modified gravity at finite temperature
J. F. Assuncao, T. Mariz, J. R. Nascimento +1
We calculate the linearized four-dimensional gravitational Chern-Simons term at the finite temperature, show its finiteness and explicitly demonstrate that its transversal part mat…
Dynamical Lorentz symmetry breaking in a 4D massless four-fermion model
J. F. Assuncao, T. Mariz, J. R. Nascimento +1
In this paper, we study the spontaneous Lorentz symmetry breaking for a four-dimensional massless four-fermion model. Our methodology is based on use of the rationalized propagator…
Radiatively induced CPT-odd Chern-Simons term in massless QED
J. F. Assuncao, T. Mariz
In this work, we study the radiative generation of the CPT-odd Lorentz-violating Chern-Simons term, arising from massless fermions. For this, we calculate the vacuum polarization t…
