Time-Dependent Magnons from First Principles
(American Chemical Society, 2020-02)
We propose an efficient and non-perturbative scheme to compute magnetic excitations for extended systems employing the framework of time dependent density functional theory. Within our approach, we drive the system out of ...
One-dimensional flat bands in twisted bilayer germanium selenide
(Nature Publishing, 2020-02-28)
Experimental advances in the fabrication and characterization of few-layer materials stacked at a relative twist of small angle have recently shown the emergence of flat energy bands. As a consequence electron interactions ...
Chemistry in Quantum Cavities: Exact Results, the Impact of Thermal Velocities, and Modified Dissociation
(American Chemical Society, 2020-09-17)
In recent years tremendous progress in the field of lightmatter interactions has unveiled that strong coupling to the modes of an optical cavity can alter chemistry even at room temperature. Despite these impressive advances, ...
Out-of-Plane Transport of 1T-TaS2/Graphene-Based van der Waals Heterostructures
(American Chemical Society, 2021-07-27)
Due to their anisotropy, layered materials are excellent candidates for studying the interplay between the inplane and out-of-plane entanglement in strongly correlated systems. A relevant example is provided by 1T-TaS2, ...
Polycyclic aromatic chains on metals and insulating layers by repetitive [3+2] cycloadditions
(Nature Publishing, 2020-03-20)
The vast potential of organic materials for electronic, optoelectronic and spintronic devices entails substantial interest in the fabrication of -conjugated systems with tailored functionality directly at insulating ...
Octopus, a computational framework for exploring light-driven phenomena and quantum dynamics in extended and finite system
(American Institute of Physics, 2020)
Over the last few years, extraordinary advances in experimental and theoretical tools have allowed us to monitor and control matter at short time and atomic scales with a high degree of precision. An appealing and challenging ...
Electron-phonon-driven three-dimensional metallicity in an insulating cuprate
(National Academy of Sciences, 2020-03-24)
The role of the crystal lattice for the electronic properties of cuprates and other high-temperature superconductors remains controversial despite decades of theoretical and experimental efforts. While the paradigm of ...
Relevance of the Quadratic Diamagnetic and Self-Polarization Terms in Cavity Quantum Electrodynamics
(American Chemical Society, 2020-04-15)
Experiments at the interface of quantum optics and chemistry have revealed that strong coupling between light and matter can substantially modify the chemical and physical properties of molecules and solids. While the ...
