A 1D topological insulator for light
(2020)
A 1D photonic topological insulator is the photonic realization of a 1D topological insulator. We show how the calculation of a topological invariant, known as the Zak phase, is a useful tool to identify different topologies ...
Design of bi-metallic devices based on the topological derivative concept
(Pergamon-Elsevier Science Ltd., 2015-01)
In this work the topological derivative concept is applied in the context of topology design of thermo-mechanical devices, where the linear elasticity system (modeled by the Navier equation) is coupled with the steady-state ...
Floquet topological transitions in a driven one-dimensional topological insulator
(American Physical Society, 2015-08)
The Su-Schrieffer-Heeger model of polyacetylene is a paradigmatic Hamiltonian exhibiting nontrivial edge states. By using Floquet theory we study how the spectrum of this one-dimensional topological insulator is affected ...
Influence of Contact Network Topology on the Spread of Tuberculosis
(2019-01-01)
This paper presents the influence of the complex networks topology on the spread of Tuberculosis with the use of the Individual-Based Model (IBM). Five complex network models were used with the IBM, namely, random, small ...
Ordering catacondensed hexagonal systems with respect to VDB topological indices
(Centro de Investigaciones en Matemática Pura y Aplicada (CIMPA) y Escuela de Matemática, San José, Costa Rica., 2016)
A topological equivalence result for a family of nonlinear difference systems having generalized exponential dichotomy
(Taylor & Francis, 2016)
We obtain sufficient conditions ensuring the topological and strong topological equivalence of two perturbed difference systems whose linear part has a property of generalized exponential dichotomy. When the exponential ...

Perspective on topological states of non-Hermitian lattices
(IOP, 2020)
The search of topological states in non-Hermitian systems has gained a strong momentum over the last two years climbing to the level of an emergent research front. In this perspective we give an overview with a focus on ...
