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 ...
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 ...
Dynamics of Confined Short-Chain alkanol in MCM-41 by Dielectric Spectroscopy: Effects of matrix and system Treatments and Filling Factor
(MDPI, 2020-03-07)
The dynamics of n-propanol confined in regular MCM-41 matrix with the pore size Dpore = 40 Å, under various matrix conditioning and sample confining conditions, using broadband dielectric spectroscopy (BDS), is reported. ...
Tunable Photodetectors via In Situ Thermal Conversion of TiS3 to TiO2
(MDPI, 2020-04-09)
In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. However, in some cases a controlled oxidation ...
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 ...
Broadband Dielectric Spectroscopy Study of Biobased Poly(alkylene 2,5-furanoate)s’ Molecular Dynamics
(MDPI, 2020-06-16)
Abstract
Poly(2,5-alkylene furanoate)s are bio-based, smart, and innovative polymers that are considered the most promising materials to replace oil-based plastics. These polymers can be synthesized using ecofriendly ...
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 ...
How dry is dry? Molecular mobility in relation to thallus water content in a lichen
(Royal Society Of Chemistry, 2020-11-07)
The increasing demand for nanoscale magnetic devices requires development of 3D magnetic nanostructures. In this regard, focused electron beam induced deposition (FEBID) is a technique of choice for direct-writing of complex ...
