	abstract = {We investigate the effect of tensile and compressive strain on the electronic structure of silicene using the density functional theory as implemented in the Quantum Espresso software. It was found that a tensile strain of about 7\% induces a semimetal-metal transition. Such a transition also occurs for 5\% applied compressive strain. Furthermore, an approximately linear relationship between an increasing strain and conduction (valence) band-Fermi energy difference was obtained for both types of strain. Engineering the band gap can widen the potential applications for mechanical modulation of the electronic properties of silicene.},

	abstract = {We demonstrate the effect of a harmonic oscillator perturbing potential on the topological phases of a Chern insulator formed from a square lattice with two quantum states per site. For a region with a non-trivial topological phase characterized by a non-zero Chern number, the perturbation introduced an energy gap closing and divided the non-trivial region into three, which possessed a topologically trivial region and two non-trivial regions. The perturbation induced singularities on the Berry curvature which led to the division of the original topologically non-trivial region.},
