Linear response time-dependent density functional theory of the Hubbard dimer
TL;DR: The asymmetric Hubbard dimer was used to study the density-dependence of the exact frequency-dependent kernel of linear-response time-dependent density functional theory as mentioned in this paper, and the limitations of the adiabatic approximation utilizing the exact ground-state functional are shown.

The Hubbard Dimer: A density functional case study of a many-body problem
TL;DR: This review explains the relationship between density functional theory and strongly correlated models using the simplest possible example, the two-site Hubbard model, and explores the behavior of the gap and the many-body Green's function, demonstrating the 'failure' of the Kohn-Sham (KS) method to reproduce the fundamental gap.

Ramon Martín Duarte,Íñigo Ruiz-Bustinza,Diego Carrascal,L. F. Verdeja,Javier Mochón,Alejandro Cores +5 more
TL;DR: In this paper, a heat transfer model was used to study the temperature evolution and hearth wear profile using a commercial software package (MATLAB version 5.0) based on computational fluid dynamics.

Spin signatures in the electrical response of graphene nanogaps

TL;DR: The electrical response of narrow graphene nanogaps in search for transport signatures stemming from spin-polarized edge states is found to be void, and the electrical transport across graphenenanogaps having perfectly defined zigzag edges does not carry any spin-related signature.
