Full analytical solution of finite-length armchair/zigzag nanoribbons

A. García-Fuente, D. Carrascal, G. Ross +1

Finite-length armchair graphene nanoribbons can behave as one dimensional topological materials, that may show edge states in their zigzag-terminated edges, depending on their widt…

Spin signatures in the electrical response of graphene nanogaps

V. M. Garcia-Suarez, A. Garcia-Fuente, D. Carrascal +6

We analyse the electrical response of narrow graphene nanogaps in search for transport signatures stemming from spin-polarized edge states. We find that the electrical transport ac…

Linear response time-dependent density functional theory of the Hubbard dimer

D. J. Carrascal, J. Ferrer, N. Maitra +1

The asymmetric Hubbard dimer is used to study the density-dependence of the exact frequency-dependent kernel of linear-response time-dependent density functional theory. The exact…

The Hubbard Dimer: A density functional case study of a many-body problem

Diego Carrascal, Jaime Ferrer, Justin C. Smith +1

This review explains the relationship between density functional theory and strongly correlated models using the simplest possible example, the two-site Hubbard model. The relation…

Unconventional magnetism in small gold organic molecules

Diego Carrascal, Lucas Fernandez-Seivane, Jaime Ferrer

We present a theoretical study of the magnetic properties of dicyclopentadienyl metallocene and phthalocyanine molecules, that contain the transition metal atoms M = Fe, Co, Ni, Cu…
