TL;DR: The SIESTA program as discussed by the authors combines finite support pseudo-atomic orbitals as basis sets, norm-conserving pseudopotentials, and a real-space grid for the representation of charge density and potentials and the computation of their associated matrix elements.

Tunable Molecular Plasmons in Polycyclic Aromatic Hydrocarbons
Alejandro Manjavacas,Federico Marchesin,Sukosin Thongrattanasiri,Peter Koval,Peter Nordlander,Daniel Sánchez-Portal,F. Javier García de Abajo +6 more
TL;DR: It is shown that chemically synthesized polycyclic aromatic hydrocarbons (PAHs) exhibit molecular plasmon resonances that are remarkably sensitive to the net charge state of the molecule and the atomic structure of the edges, and suggest new paradigms for electro-optical modulation and switching, single-electron detection, and sensing using individual molecules.

Universal magnetic properties of sp3-type defects in covalently functionalized graphene
Elton J. G. Santos,Elton J. G. Santos,Elton J. G. Santos,Andrés Ayuela,Andrés Ayuela,Daniel Sánchez-Portal,Daniel Sánchez-Portal +6 more
TL;DR: In this article, the effect of sp3-type defects created by different covalent functionalizations on the electronic and magnetic properties of graphene was studied using density-functional calculations, and it was shown that the induced magnetic properties are universal, in the sense that they are largely independent of the particular adsorbates considered.
Journal ArticleDOI
Different origins of the ferromagnetic order in (Ga,Mn)As and (Ga,Mn) N
TL;DR: In this paper, the electronic structures of (Ga,Mn)As and wurtzite (Mn, As) were calculated using density functional theory in both the local spin density approximation (LSDA) and the local density approximation(LDA+U) scheme, that was implemented in the code SIESTA.
