Unconventional Approaches in Coordination Chemistry and Organometallic Reactivity
(American Chemical Society, 2021-03-23)
This contribution highlights a number of approaches developed by coordination and organometallic chemists that go beyond mainstream inorganic reactivity. A few of these strategies have been known for decades and are ...
Unravelling the Intertwined Atomic and Bulk Nature of Localised Excitons by Attosecond Spectroscopy
(Springer, 2021-02-15)
The electro-optical properties of most semiconductors and insulators of technological interest are dominated by the presence of electron-hole quasi-particles, called excitons. The manipulation of excitons in dielectrics ...
Coherent coupling between vortex bound states and magnetic impurities in 2D layered superconductors
(Nature, 2021-08-03)
Bound states in superconductors are expected to exhibit a spatially resolved electron-hole asymmetry which is the hallmark of their quantum nature. This asymmetry manifests as oscillations at the Fermi wavelength, which ...
In-Plane Anisotropic Optical and Mechanical Properties of Two-Dimensional MoO3
(Nature, 2021-04-12)
Molybdenum trioxide (MoO3) in-plane anisotropy has increasingly attracted the attention of the scientific community in the last few years. Many of the observed in-plane anisotropic properties stem from the anisotropic ...
Gold nanoparticles endowed with low-temperature colloidal stability by cyclic polyethylene glycol in ethanol
(The Royal Society of Chemistry, 2021-09-07)
The colloidal stability of metal nanoparticles is tremendously dependent on the thermal behavior of polymer brushes. Neat polyethylene glycol (PEG) presents an unconventional upper critical solution temperature in ethanol, ...
Theory of spin-orbit interactions in electronic transport and light scattering at the mesoscale.
(2021-02-03)
En esta Tesis, estudiamos los fundamentos teóricos de las interacciones de espín-órbita en dos de las ramas más prometedoras de la física de hoy en día, la espintrónica y la nanofotónica. Nos enfocamos en entender las ...
Overcoming the Exciton Binding Energy in Two-Dimensional Perovskite Nanoplatelets by Attachment of Conjugated Organic Chromophores
(Nature, 2020-04-20)
In this work we demonstrate a novel approach to achieve efficient charge separation in dimensionally and dielectrically confined two-dimensional perovskite materials. Two-dimensional perovskites generally exhibit large ...
Conditional Wave Function Theory: A Unified Treatment of Molecular Structure and Nonadiabatic Dynamics
(American Chemical Society, 2021-11-09)
[EN] We demonstrate that a conditional wave function theory enables a unified and efficient treatment of the equilibrium structure and nonadiabatic dynamics of correlated electron-ion systems. The conditional decomposition ...
Nematicity Arising from a Chiral Superconducting Ground State in Magic-Angle Twisted Bilayer Graphene under In-Plane Magnetic Fields
(American Physical Society, 2021-09-13)
Recent measurements of the resistivity in magic-angle twisted bilayer graphene near the superconducting transition temperature show twofold anisotropy, or nematicity, when changing the direction of an in-plane magnetic ...
Light-Driven Extremely Nonlinear Bulk Photogalvanic Currents
(American Physical Society, 2021-09-13)
We predict the generation of bulk photocurrents in materials driven by bichromatic fields that arc circularly polarized and corotating. The nonlinear photocurrents have a fully controllable directionality and amplitude ...
