Journal ArticleDOI
Quantum electrodynamical density-functional theory: Bridging quantum optics and electronic-structure theory
Michael Ruggenthaler,Johannes Flick,Camilla Pellegrini,Heiko Appel,Ilya V. Tokatly,Angel Rubio +5 more
TL;DR: In this paper, a hierarchy of density-functional-type theories that describe the interaction of charged particles with photons and introduce the appropriate Kohn-Sham schemes are presented for the Coulomb gauge model of quantum electrodynamics.
Journal ArticleDOI
Optimized Effective Potential for Quantum Electrodynamical Time-Dependent Density Functional Theory
Camilla Pellegrini,Johannes Flick,Ilya V. Tokatly,Ilya V. Tokatly,Heiko Appel,Angel Rubio,Angel Rubio +6 more
TL;DR: The present formalism opens the path to a first-principles description of correlated electron-photon systems, bridging the gap between electronic structure methods and quantum optics for real material applications.
Journal ArticleDOI
Real-space anisotropy of the superconducting gap in the charge-density wave material 2H-NbSe2
Antonio Sanna,Camilla Pellegrini,Eva Liebhaber,Kai Rossnagel,Katharina J. Franke,E. K. U. Gross +5 more
TL;DR: In this paper , a scanning tunneling microscopy (STM) and ab-initio study of the anisotropic superconductivity of 2H-NbSe 2 in the charge-density-wave (CDW) phase is presented.
Journal ArticleDOI
Ab initio study of ultrafast demagnetization of elementary ferromagnets by terahertz versus optical pulses
TL;DR: In this article , the authors present an ab initio time-dependent density functional theory study of the ultrafast demagnetization of elemental ferromagnets subject to terahertz (THz) laser pumping compared to optical laser pumping.
Journal ArticleDOI
Eliashberg theory with ab-initio Coulomb interactions: a minimal numerical scheme applied to layered superconductors
TL;DR: In this paper , a minimal approach to include static Coulomb interactions in Eliashberg theory of superconductivity from first principles is presented, which can be easily implemented in any existing EliASHberg code (isotropic or anisotropic) to avoid the standard use of the semi-empirical parameter μ∗ , which adds unnecessary uncertainty to T c predictions.
