Charging dynamics of dopants in helium nanoplasmas
Andreas Heidenreich, Barbara Grüner, Dominik Schomas +3
We present a combined experimental and theoretical study of the charging dynamics of helium nanodroplets doped with atoms of different species and irradiated by intense near-infrar…
Analytic gradients for natural orbital functional theory
Ion Mitxelena, Mario Piris
The analytic energy gradients with respect to nuclear motion are derived for natural orbital functional (NOF) theory. The resulting equations do not require to resort to linear-res…
Similar temperature scale for valence changes in Kondo lattices with different Kondo temperatures
K. Kummer, C. Geibel, C. Krellner +4
The Kondo model predicts that both the valence at low temperatures and its temperature dependence scale with the characteristic energy T_K of the Kondo interaction. Here, we study…
Valley Hall Effect and Nonlocal Transport in Strained Graphene
Xian-Peng Zhang, Chunli Huang, Miguel A. Cazalilla
Graphene subject to high levels of shear strain leads to strong pseudo-magnetic fields resulting in the emergence of Landau levels. Here we show that, with modest levels of strain,…
Probing low-energy hyperbolic polaritons in van der Waals crystals with an electron microscope
Alexander A. Govyadinov, Andrea Konečná, Andrey Chuvilin +8
Van der Waals (vdW) materials exhibit intriguing structural, electronic and photonic properties. Electron Energy Loss Spectroscopy (EELS) within Scanning Transmission Electron Micr…
Tunneling of Hybridized Pairs of Electrons through a One-Dimensional Channel
Godfrey Gumbs, Danhong Huang, Julie Hon +2
Recently, the electron transport through a quasi-one dimensional (quasi-1D) electron gas was investigated experimentally as a function of the confining potential. We present a phys…
