Dirac fermions on a surface with localized strain
Samuel B. B. Almeida, J. E. G. Silva, C. A. S. Almeida
We study the influence of a localized Gaussian deformation on massless Dirac fermions confined to a two-dimensional curved surface. Both in-plane and out-of-plane displacements are…

Perturbative solutions for compact objects in (2+1)-dimensional Bopp-Podolsky electrodynamics
R. V. Maluf, J. E. G. Silva, C. A. S. Almeida +1
We investigate the space-time geometry generated by compact objects in (2+1)-dimensional Bopp-Podolsky electrodynamics. Inspired by previous studies where the Bopp-Podolsky field a…
