Network dynamics in nanofilled polymers
(Nature Publishing, 2016-04-25)
It is well accepted that adding nanoparticles (NPs) to polymer melts can result in significant property improvements. Here we focus on the causes of mechanical reinforcement and present rheological measurements on favourably ...
Single Chiral Skyrmions in Ultrathin Magnetic Films
(MDPI, 2018-11-11)
The stability and sizes of chiral skyrmions in ultrathin magnetic films are calculated accounting for the isotropic exchange, Dzyaloshinskii-Moriya exchange interaction (DMI), and out-of-plane magnetic anisotropy within ...
Real-Time Propagation TDDFT and Density Analysis for Exciton Coupling Calculations in Large Systems
(American Chemical Society, 2019-06)
Photoactive systems are characterized by their capacity to absorb the energy of light and transform it. Usually, more than one chromophore is involved in the light absorption and excitation transport processes in complex ...
Identifying substitutional oxygen as a prolific point defect in monolayer transition metal dichalcogenides
(Nature, 2019-07-29)
Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent observation in ...
How Confinement Affects the Nucleation, Crystallization, and Dielectric Relaxation of Poly(butylene succinate) and Poly(butylene adipate) Infiltrated within Nanoporous Alumina Templates
(ACS Publications, 2019-10-17)
This work describes the successful melt infiltration of poly(butylene succinate) (PBS) and poly(butylene adipate) (PBA) within 70 nm diameter anodic aluminum oxide (AAO) templates. The infiltrated samples were characterized ...
Light−Matter Response in Nonrelativistic Quantum Electrodynamics
(American Chemical Society, 2019-11)
We derive the full linear-response theory for nonrelativistic quantum electrodynamics in the long wavelength limit and provide a practical framework to solve the resulting equations by using quantum-electrodynamical ...
Multiflat Bands and Strong Correlations in Twisted Bilayer BoronNitride: Doping-Induced Correlated Insulator and Superconductor
(American Chemical Society, 2019-08)
Two-dimensional materials, obtained by van der Waals stacking of layers, are fascinating objects of contemporary condensed matter research, exhibiting a variety of new physics. Inspired by the breakthroughs of twisted ...
Two-magnon bound state causes ultrafast thermally induced magnetisation switching
(Nature Publishing Group, 2013-11)
There has been much interest recently in the discovery of thermally induced magnetisation switching using femtosecond laser excitation, where a ferrimagnetic system can be switched deterministically without an applied ...
Efficient Gate-tunable light-emitting device made of defective boron nitride nanotubes: from ultraviolet to the visible
(Nature Publishing Group, 2013-09)
Boron nitride is a promising material for nanotechnology applications due to its two-dimensional graphene-like, insulating, and highly-resistant structure. Recently it has received a lot of attention as a substrate to grow ...
Long-lived oscillatory incoherent electron dynamics in molecules: trans-polyacetylene oligomers
(IOP Publishing, 2013-04)
We identify an intriguing feature of the electron-vibrational dynamics of molecular systems via a computational examination of trans-polyacetylene oligomers. Here, via the vibronic interactions, the decay of an electron ...
