Strong gravitational lensing in a spacetime with topological charge within the Eddington-inspired Born-Infeld gravity
C. Furtado, J. R. Nascimento, A. Yu. Petrov +2
In this work we calculate the angular deflection of light in the strong field limit in two spacetimes which were previously studied within the Eddington-inspired Born-Infeld gravit…
Probing the structure and composition of van der Waals heterostructures using the nonlocality of Dirac plasmons in the terahertz regime
I. R. Lavor, L. S. R. Cavalcante, Andrey Chaves +2
Dirac plasmons in graphene are very sensitive to the dielectric properties of the environment. We show that this can be used to probe the structure and composition of van der Waals…
Solitary oscillations and multiple antikink-kink pairs in the double sine-Gordon model
Fabiano C. Simas, Fred C. Lima, K. Z. Nobrega +1
We study kink-antikink collisions in a particular case of the double sine-Gordon model depending on only one parameter . The scattering process of large kink-antikink shows the…
Effect of zitterbewegung on the propagation of wave packets in ABC-stacked multilayer graphene: an analytical and computational approach
I. R. Lavor, D. R. da Costa, Andrey Chaves +4
The time evolution of a low-energy two-dimensional Gaussian wave packet in ABC-stacked -layer graphene (ABC-NLG) is investigated. Expectation values of the position of c…
