The present work sought to deduce the alpha decay theory based on quantum tunneling and using approximations in the resolution of the Schrödinger equation for Coulomb potential. It was possible to find the alpha decay constant analytically. One of t

Abstract In recent years the research about topological photonic structures has been a very attractive topic in nanoscience from both a basic science and a technological point of view. In this work we propose a two-dimensional topological photonic st

In this work, we propose a 2D topological photonic system of Si rods by using a simple geometric perturbation. We obtained two phases, type A and type B, which are topological and trivial, respectively.
