Survival of Floquet-Bloch States in the Presence of Scattering
(American Chemical Society, 2021-06-23)
Floquet theory has spawned many exciting possibilities for electronic structure control with light, with enormous potential for future applications. The experimental demonstration in solids, however, remains largely ...
Coexistence of Superconductivity and Spin-Splitting Fields in Superconductor/Ferromagnetic Insulator Bilayers of Arbitrary Thickness
(American Physical Society, 2021-05-19)
Ferromagnetic insulators (FI) can induce a strong exchange field in an adjacent superconductor (S) via the magnetic proximity effect. This manifests as spin splitting of the BCS density of states of the superconductor, an ...
Crystallization of a Self-Assembling Nucleator in Poly(L-lactide) Melt
(American Chemical Society, 2021-09-01)
[EN]In the present work, crystallization of a soluble nucleator N, N′, N″-tricyclohexyl-1,3,5-benzenetricarboxylamide (TMC-328) in a poly(l-lactic acid) (PLLA) matrix has been studied at different temperatures. Based on ...
Realization of nearly dispersionless bands with strong orbital anisotropy from destructive interference in twisted bilayer MoS2
(Nature Research, 2021-09)
[EN]Recently, the twist angle between adjacent sheets of stacked van der Waals materials emerged as a new knob to engineer correlated states of matter in two-dimensional heterostructures in a controlled manner, giving rise ...
Simulating Vibronic Spectra without Born-Oppenheimer Surfaces
(ACS Publications, 2021-04-01)
We show how linear vibronic spectra in molecular systems can be simulated efficiently using first-principles approaches without relying on the explicit use of multiple Born-Oppenheimer potential energy surfaces. We demonstrate ...
High-Harmonic Generation from Spin-Polarised Defects in Solids
(Nature, 2020-01-31)
The generation of high-order harmonics in gases enabled to probe the attosecond electron dynamics in atoms and molecules with unprecedented resolution. Extending these techniques to solids, which were originally developed ...
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 ...
Effect of environmental humidity on the ionic transport of poly(ethylene oxide) thin films by local dielectric spectroscopy
(RSC, 2020-03-03)
The effect of humidity on the ionic transport in the amorphous phase of poly(ethylene
oxide) thin films has been studied by via local dielectric spectroscopy. We explored a
controlled humidity range between 15 %RH and ...
