Dynamics of localized solutions in three core coupled waveguides with quasi-periodic nonlinearity

Bruno M. Miranda, Ardiley T. Avelar, Wesley B. Cardoso +1

In this paper we investigate the behavior of localized solutions, specifically solitons, in a system of three coupled waveguides. The nonlinearity is modeled by a quasi-periodic mo…

Local null controllability of a quasi-linear system and related numerical experiments

Enrique Fernández-Cara, Juan Límaco, Yuri Thamsten +1

This paper concerns the null control of quasi-linear parabolic systems where the diffusion coefficient depends on the gradient of the state variable. In our main theoretical result…

A rotating black hole in a Hernquist dark matter halo: horizon geometry, thermodynamics, and quantum emission

A. A. Araújo Filho, Arun Kumar, N. Heidari +3

We investigate the geometrical, thermodynamic, and quantum emission properties of a rotating black hole immersed in a Hernquist dark matter halo. Starting from a static black hole…

Compact, long-range and vacuumless regimes controlled by scalar fields in two-dimensional flat and five-dimensional warped geometries

Elisama E. M. Lima, Dionisio Bazeia

We investigate the presence of compact, long-range, and vacuumless regimes in models described by real scalar fields in 2D flat and 5D warped geometries. In the two-dimensional cas…

One-loop contributions in Lorentz-violating scalar QED with nonminimal coupling

F. M. Belchior, J. R. Nascimento, A. Yu. Petrov +1

In the context of pertubative aspects of Lorentz-violating theories, we study the divergent one-loop two-point functions of a Lorentz-violating (LV) extension of scalar QED contain…

Geometrically constrained multi-kink configurations in generalized impurity-doped field theories

D. Bazeia, M. A. Liao, M. A. Marques

This short communication investigates impurity coupling in generalized field theories where scalar coupling is introduced directly at the level of the kinetic and gradient contribu…
