Photon emission and quantum transport in nanoplasmonic cavities
(2020-09-04)
[EN]The study of light–matter interaction has drawn through the years more and more interest. With the improvement of the techniques used for building electromagnetic cavities, it is now possible to couple cavities with ...
Parameter-Free Hybridlike Functional Based on an Extended Hubbard Model: DFT Plus U Plus V
(American Physical Society, 2020-10-13)
In this paper, we propose an energy functional at the level of DFT U + V that allows us to compute self-consistently the values of the onsite interaction, Hubbard U and Hund J, as well as the intersite interaction V. This ...
Synthesis and characterization of cyclic polysthers with controlled orientation of the dipolar moment along the chain contour
(2020-09-09)
En esta tesis, se estudia la síntesis de poli (glicidil fenil éter) cíclico. Se emplearon diferentes sistemas de iniciación para generar precursores lineales con características moleculares controladas y microestructuras ...
Tunable 3D/2D magnetism in the (MnBi2Te4)(Bi2Te3)mtopological insulators family
(Nature, 2020-08-03)
Feasibility of many emergent phenomena that intrinsic magnetic topological insulators (TIs) may host depends crucially on our ability to engineer and efficiently tune their electronic and magnetic structures. Here we report ...
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 ...
Mid-infrared nanophotonics with hyperbolic phonon polaritons
(2020-03-23)
El nitruro de boro hexagonal (h-BN) es un material especialmente interesante en óptica subdifracional en el infrarrojo medio. h-BN es un cristal polar que exhibe fonón-polaritones en sus dos bandas Reststrahlen en el ...
Topologization of Beta-Antimonene on Bi2Se3 Via Proximity Effects
(Nature, 2020-09-03)
Topological surface states usually emerge at the boundary between a topological and a conventional insulator. Their precise physical character and spatial localization depend on the complex interplay between the chemical, ...
Electronic Decoupling of Polyacenes from the Underlying Metal Substrate bysp(3)Carbon Atoms
(Nature, 2020-09-15)
Many organic molecules exhibit interesting electronic and magnetic properties, but as they are deposited onto a metallic substrate, their hybridisation often impacts on the observed characteristics. Here, the authors report ...
Giant Exciton Mott Density in Anatase TiO2
(American Physical Society, 2020-09-10)
Elucidating the carrier density at which strongly bound excitons dissociate into a plasma of uncorrelated electron-hole pairs is a central topic in the many-body physics of semiconductors. However, there is a lack of ...
How Circular Dichroism in Time and Angle-Resolved Photoemission Can Be Used to Spectroscopically Detect Transient Topological States in Graphene
(American Physical Society, 2020-10-19)
Pumping graphene with circularly polarized light is the archetype of light-tailoring topological bands. Realizing the induced Floquet-Chern-insulator state and demonstrating clear experimental evidence for its topological ...
