In this work we study how CPT-odd Maxwell-Carroll-Field-Jackiw (MCFJ) electrodynamics
as well as a dimension-5 extension of it affect the optical activity of continuous media. The …

We consider a (2+ 1)-dimensional modified electrodynamics endowed with terms that are
either Lorentz invariant or Lorentz violating and involve an ever-increasing number of …

In this paper we present an Abelian Higgs model in which the scalar field is nonminimally
coupled with the Maxwell field. This model gives rise to the Bopp-Podolsky theory in the …

We perform the BFV-BRST quantization of the fourth-order Pais-Uhlenbeck oscillator (PUO)
for the first time. We show that although the PUO is not naturally constrained in the sense of …

We consider, in Minkowski spacetime, higher-order Maxwell Lagrangians with terms
quadratic in the derivatives of the field strength tensor, and study their degrees of freedom …

In this work we study the Higgs mechanism and the Debye shielding for the Bopp–Podolsky
theory of electrodynamics. We find that not only the massless sector of the Podolsky theory …

In this paper, we investigate the so-called Bopp–Podolsky electrodynamics. The Bopp–
Podolsky electrodynamics is a prototypical gradient field theory with weak nonlocality in …

The aim of this work is to discuss and explore some generalized aspects of generation of
photon mass respecting gauge symmetry. We introduce generalized Stueckelberg and …

We consider the interaction between a charged scalar boson and the Bopp–Podolsky gauge
fields. The Bopp–Podolsky (BP) electrodynamics possesses both massive and massless …

In this paper, we investigate certain aspects of Lee–Wick electrodynamics near a
semitransparent planar mirror. Specifically, we derive the modified propagator for the Lee …
