Spontaneous symmetry breaking in models with second-class constraints
C. A. Escobar, Román Linares
In this work the spontaneous symmetry breaking in certain nonlinear theories with second-class constraints is explored. Using the Dirac's method we perform an analysis of the const…
Testing the scalar sector of the Standard-Model Extension with neutron gravity experiments
C. A. Escobar, A. Martín-Ruiz, A. M. Escobar-Ruiz +1
In the present study we analyse, within the scalar sector of the Standard-Model Extension (SME) framework, the influence of a spontaneous Lorentz symmetry breaking on gravitational…
Critical phenomena in light-matter systems with collective matter interactions
Ricardo Herrera Romero, Miguel Angel Bastarrachea-Magnani, Román Linares
We study the quantum phase diagram and the onset of quantum critical phenomena in a generalized Dicke model that includes collective qubit-qubit interactions. By employing semiclas…
Hamiltonian analysis of ModMax nonlinear electrodynamics in the first order formalism
C. A. Escobar, Román Linares, B. Tlatelpa-Mascote
In this work we study the so-called ModMax nonlinear electrodynamics, which is a novel model designed to preserve duality rotations and conformal transformations, such as the Maxwe…
Scalar Casimir effect for a conducting cylinder in a Lorentz violating background
A. M. Escobar-Ruiz, A. Martín-Ruiz, Escobar C. A. +1
Following a field-theoretical approach, we study the scalar Casimir effect upon a perfectly conducting cylindrical shell in the presence of spontaneous Lorentz symmetry breaking. T…
Nonlinear extensions of gravitating dyons: from NUT wormholes to Taub-Bolt instantons
Daniel Flores-Alfonso, Román Linares, Marco Maceda
Recent work has shown the existence of a unique nonlinear extension of electromagnetism which preserves conformal symmetry and allows for the freedom of duality rotations. Moreover…
