High Harmonics and Isolated Attosecond Pulses from MgO
(American Physical Society, 2021-01-08)
On the basis of real-time ab initio calculations, we study the nonperturbative interaction of two-color laser pulses with MgO crystal in the strong-field regime to generate isolated attosecond pulses from high-harmonic ...
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 ...
Complex Networks Reveal Emergent Interdisciplinary Knowledge in Wikipedia
(Springer Nature, 2021-05-25)
In the last 2 decades, a great amount of work has been done on data mining and knowledge discovery using complex networks. These works have provided insightful information about the structure and evolution of scientific ...
Inelastic Helium Atom Scattering from Sb2Te3(111): Phonon Dispersion, Focusing Effects and Surfing
(Royal Society Of Chemistry, 2021-04-07)
We present an experimental study of inelastic scattering processes on the (111) surface of the topological insulator Sb2Te3 using helium atom scattering. In contrast to other binary topological insulators such as Bi2Se3 ...
Evidence for a Spin Acoustic Surface Plasmon from Inelastic Atom Scattering
(Nature, 2021-01-15)
Closed-shell atoms scattered from a metal surface exchange energy and momentum with surface phonons mostly via the interposed surface valence electrons, i.e., via the creation of virtual electron-hole pairs. The latter can ...
Crowded Solutions of Single-Chain Nanoparticles under Shear Flow
(Royal Society Of Chemistry, 2021-03-04)
Single-chain nanoparticles (SCNPs) are ultrasoft objects obtained through purely intramolecular cross-linking of single polymer chains. By means of computer simulations with implemented hydrodynamic interactions, we ...
Focusing of in-plane hyperbolic polaritons in van der Waals crystals with tailored infrared nanoantennas
(American Association for the Advancement of Science, 2021-10)
[EN]Phonon polaritons (PhPs)-light coupled to lattice vibrations-with in-plane hyperbolic dispersion exhibit ray-like propagation with large wave vectors and enhanced density of optical states along certain directions on ...
Ab Initio Molecular Dynamics of Hydrogen on Tungsten Surfaces
(Royal Society Of Chemistry, 2021-04-07)
The dissociation process of hydrogen molecules on W(110) was studied using density functional theory and classical molecular dynamics. We have calculated the dissociation probability for molecules with energies below 300 ...
The ferroelectric photo ground state of SrTiO3: Cavity materials engineering
(National Academy of Sciences, 2021-08-03)
Optical cavities confine light on a small region in space, which can result in a strong coupling of light with materials inside the cavity. This gives rise to new states where quantum fluctuations of light and matter can ...
A Dissolution Model of Alite Coupling Surface Topography and Ions Transport under Different Hydrodynamics Conditions at Microscale
(Elsevier, 2021-04)
Portland cement is the most produced material in the world. The hydration process of cement consists of a group of complex chemical reactions. In order to investigate the mechanism of cement hydration, it is vital to study ...
