Klein tunneling on Bour surfaces with topological defects
The existence of a curved graphene sheet with the geometry of a Bour surface B n is
supposed, such as the catenoid (or helicoid), B 0, and the classical Enneper surface, B 2 …

Tunable transmittance in anisotropic two-dimensional materials
A uniaxial strain applied to graphenelike materials moves the Dirac nodes along the
boundary of the Brillouin zone. An extreme case is the merging of the Dirac node positions …

Aspects of the polynomial affine model of gravity in three dimensions: With focus in the cosmological solutions
The polynomial affine gravity is a model that is built up without the explicit use of a metric
tensor field. In this article we reformulate the three-dimensional model and, given the …
