The Bi/Si(111) (root 3 x root 3)R30 degrees trimer phase offers a prime example of a giant spin-orbit splitting of the electronic states at the interface with a semiconducting substrate. We have performed a detailed angle-resolved photoemission spectroscop ...
The Gross-Pitaevskii equation for Bose-Einstein condensates of exciton polaritons in two-dimensional traps is solved analytically accounting for spin-dependent polariton-polariton interactions. We show that the ground state of the condensate is characteriz ...
Resonant inelastic x-ray scattering in the soft x-ray regime has been profiting much from technical advances that have lowered considerably the instrumental linewidth. At the ADRESS beam line of the Swiss Light Source the SAXES spectrometer can be used to ...
A remarkable feature of exciton-polaritons is the strongly spin-dependent polariton-polariton interaction, which has been predicted to result in the formation of spin rings in real space [Shelykh et al., Phys. Rev. Lett. 100, 116401 (2008)]. Here we experi ...
Conditions for a transition from the insulator (I) to metal (M) state in the electron system of highly oriented pyrolytic graphite (HOPG) have been studied by means of magnetotransport measurements in a broad temperature range (0.3–150 K). In magnetic fiel ...
The ligand-field (LF) transition energies of the Co(NH3)(6)(3+) ion have been computed with multiconfiguration quasidegenerate second-order perturbation theory (MCQDPT2). The water solvent was treated with the polarizable continuum model (PCM), and the env ...
The importance of developing predictive modeling tools has considerably increased with the diffusion of nanoscale technologies, in which strained layers and heterojunctions determine the materials modeling complexity. A self--consistent Poisson--Schroeding ...
We present a detailed analysis of the addition-elimination reaction pathways for the gas-phase conversion of molecular hydrogen and methane on FeO(+) to water and methanol, respectively, using first-principles calculations. These two reactions represent pa ...
Structural and electronic properties of the lambda-MnO2(001) surface are investigated applying density functional theory approach. The calculations show that all Mn ions at unreconstructed smooth surface preserve the +4 oxidation state observed in the bulk ...
High resolution amplitude and phase of light fields emerging from a 2-μm-period amplitude grating are measured for different wavelengths. The amplitude gratings lead to highly periodic patterns caused by the Talbot effect. Such patterns reach periodicities ...
