Creating stable Floquet–Weyl semimetals by laser-driving of 3D Dirac materials
(Nature Publishing, 2017-01-17)
Tuning and stabilizing topological states, such as Weyl semimetals, Dirac semimetals or topological insulators, is emerging as one of the major topics in materials science. Periodic driving of many-body systems offers a ...
Electronic non-adiabatic dynamics in enhanced ionization of isotopologues of hydrogen molecular ions from the exact factorization perspective
(Royal Society of Chemistry, 2017-03-28)
It was recently shown that the exact potential driving the electron's dynamics in enhanced ionization of H-2(+) can have large contributions arising from dynamic electron-nuclear correlation, going beyond what any ...
Quantum plasmonics: from jellium models to ab initio calculations
(Walter de Gruyter, 2016-08)
Light-matter interaction in plasmonic nanostructures is often treated within the realm of classical optics. However, recent experimental findings show the need to go beyond the classical models to explain and predict the ...
Unraveling materials Berry curvature and Chern numbers from real-time evolution of Bloch states
(Natlacad Sciences, 2019-03-05)
Materials can be classified by the topological character of their electronic structure and, in this perspective, global attributes immune to local deformations have been discussed in terms of Berry curvature and Chern ...
Orbital magneto-optical response of periodic insulators from first principles
(Springer, 2019-03-06)
Magneto-optical response, i.e. optical response in the presence of a magnetic field, is commonly used for characterization of materials and in optical communications. However, quantum mechanical description of electric and ...
Exciton control inaroom temperature bulk semiconductor withcoherent strain pulses
(American Association for the Advancement of Science, 2019-11)
Controlling the excitonic optical properties of room temperature semiconductors using time-dependent perturbations is key to future optoelectronic applications. The optical Stark effect in bulk and low-dimensional materials ...
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 ...
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 ...
