Book
Quantum theory of the electron liquid
TL;DR: In this paper, the Hartree-Fock approximation is used to approximate the linear response of an interacting electron liquid and the perturbative calculation of linear response functions is performed. But the results are limited to the one-dimensional electron gas at high magnetic field.
Book
Electronic density functional theory : recent progress and new directions
TL;DR: In this paper, the LSDF approach was used to calculate the magnetic interaction in Magnetic Metal Alloys via a LSDF-based approach, and the results showed that the van der Waals interaction is related to the Kohn-Sham Eigenvalues.

Highly confined low-loss plasmons in graphene–boron nitride heterostructures
Achim Woessner,Mark B. Lundeberg,Yuanda Gao,Alessandro Principi,Pablo Alonso-González,Matteo Carrega,Kenji Watanabe,Takashi Taniguchi,Giovanni Vignale,Marco Polini,James Hone,Rainer Hillenbrand,Frank H. L. Koppens +12 more
TL;DR: In this paper, the dispersion and plasmon damping of propagating plasmons in high-quality graphene encapsulated between two films of hexagonal nanophoton nitride (h-BN).
Book
Quantum Theory of the Electron Liquid
TL;DR: In this article, the physics of the interacting electron liquid in a broad variety of systems, including metals, semiconductors, artificial nano-structures, atoms and molecules, is discussed.

TL;DR: This Article exploits near-field microscopy to image propagating plasmons in high-quality graphene encapsulated between two films of hexagonal boron nitride (h-BN), and finds unprecedentedly low plasmon damping combined with strong field confinement and confirms the high uniformity of this plAsmonic medium.
