Implementation of the two-dimensional electrostatic particle-in-cell method
We provide a guide to implementing the particle-in-cell algorithm, which is useful for simulating diverse phenomena in plasmas. We focus on two-dimensional systems which have vector fields with three Cartesian components ... -
Speeches and journeys in the corporeality of time-space [Discursos y recorridos en la corporalidad del tiempo-espacio]
"The philosophy of Kant reveals, as he expressed it, a ""awakening of the Dogmatic Dream"", which is based on a copernicanic twist in Western philosophy. This article displays some reflections on this philosophical turn ... -
Symmetry-protected metallic and topological phases in penta-materials
We analyze the symmetry and topological features of a family of materials closely related to penta-graphene, derived from it by adsorption or substitution of different atoms. Our description is based on a novel approach, ... -
