Effective electromagnetic Lagrangians in the derivative expansion method
R. Martínez von Dossow, Luis F. Urrutia
We calculate the effective electromagnetic Lagrangian up to the lowest-order corrections in the derivatives for two fermionic systems of interest in condensed matter physics in the…
Momentum non-conservation in a scalar quantum field theory with a planar interface
Daniel G. Velázquez, R. Martínez von Dossow, Luis F. Urrutia
Motivated by the recent interest aroused by non-dynamical axionic electrodynamics in the context of topological insulators and Weyl semimetals, we discuss a simple model of the mag…
Lorentz invariance violation and the CPT-odd electromagnetic response of a tilted anisotropic Weyl semimetal
Andrés Gómez, R. Martínez von Dossow, A. Martín-Ruiz +1
We derive the electromagnetic response of a particular fermionic sector in the minimal QED contribution to the Standard Model Extension (SME), which can be physically realized in t…
A Five Dimensional Perspective on Many Particles in the Snyder basis of Double Special Relativity
J. M. Lorenzi, R. Montemayor, L. F. Urrutia
After a brief summary of Double Special Relativity (DSR), we concentrate on a five dimensional procedure, which consistently introduce coordinates and momenta in the corresponding…
Perturbative Hamiltonian constraints for higher order theories
S. A. Martinez, R. Montemayor, L. F. Urrutia
We present a method for constructing a consistent low energy canonical formalism for higher order time-derivative theories, extending the Dirac method to include perturbative Hamil…
Duality for massive spin two theories in arbitrary dimensions
B. Gonzalez, A. Khoudeir, R. Montemayor +1
Using the parent Lagrangian approach we construct a dual formulation, in the sense originally proposed by Curtright and Freund, of a massive spin two Fierz-Pauli theory in arbitrar…
