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 ...
Identifying optimal technological portfolios for European power generation towards climate change mitigation: A robust portfolio analysis approach
(Elsevier, 2019)
Here, an integrative approach is proposed to link integrated assessment modelling results from the GCAM model with a novel portfolio analysis framework. This framework comprises a bi-objective optimisation model, Monte ...
Southward re-distribution of tropical tuna fisheries activity can be explained by technological and management change
(John Wiley & Sons Ltd, 2020)
There is broad evidence of climate change causing shifts in fish distribution worldwide, but less is known about the response of fisheries to these changes. Responses to climate-driven shifts in a fishery may be constrained ...
Impact of social and mobility restrictions in Parkinson's disease during COVID-19 lockdown
(Springer, 2021-08-30)
Background The consequences of strict COVID-19 mobility restrictions on motor/non-motor features in Parkinson's disease (PD) have not been systematically studied but worse mobility and quality of life have been reported. ...
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 ...
Greenhouse gas observation network design for Africa
(TELLUS SERIES B-CHEMICAL AND PHYSICAL METEOROLOGY, 2020)
An optimal network design was carried out to prioritise the installation or refurbishment of greenhouse gas (GHG) monitoring stations around Africa. The network was optimised to reduce the uncertainty in emissions across ...
Plasmonic Antenna Coupling to Hyperbolic Phonon-Polaritons for Sensitive and fast Mid-Infrared Photodetection with Graphene
(Nature, 2020-09-25)
Integrating and manipulating the nano-optoelectronic properties of Van der Waals heterostructures can enable unprecedented platforms for photodetection and sensing. The main challenge of infrared photodetectors is to funnel ...
