Angular Dependences of Third Harmonic Generation from Microdroplets
J. Kasparian, B. Krämer, J. P. Dewitz +9
We present experimental and theoretical results for the angular dependence of third harmonic generation (THG) of water droplets in the micrometer range (size parameter )…
High-T_c Superconductivity and Shadow State Formation in YBa_{2}Cu_{3}O_{6+δ} and Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}
S. Grabowski, J. Schmalian, K. H. Bennemann
The normal and superconducting state of YBa_{2}Cu_{3}O_{6+δ} and Bi_{2}Sr_{2}CaCu_{2}O_{8+δ} are investigated by using the mono- and bilayer Hubbard model within the fluctuation ex…
Theory for the giant magneto-optical Kerr rotation in CeSb
U. Pustogowa, W. Huebner, K. H. Bennemann
We calculate the linear magneto-optical Kerr rotation angle for CeSb in the near-infrared spectral range. Using an exact formula for large Kerr rotation angles and a simplified ele…
Symmetry Analysis of the Nonlinear Optical Response: New Magneto-Optical Effect in Second Harmonic Generation
A. Daehn, W. Huebner, K. H. Bennemann
Using symmetry arguments we show how optical second harmonic generation (SHG) can be used to detect antiferromagnetism at surfaces and in thin films. Based on the group theoretical…
Multiple-Scattering Theory of X-Ray Magnetic Circular Dichroism: Implementation and Results for Iron K-edge
Ch. Brouder, M. Alouani, K. H. Bennemann
An implementation of the multiple-scattering approach to x-ray magnetic circular dichroism (XMCD) in K-edge x-ray absorption spectroscopy is presented. The convergence problems due…
Theory for Dynamical Short Range Order and Fermi Surface Volume in Strongly Correlated Systems
J. Schmalian, M. Langer, S. Grabowski +1
Using the fluctuation exchange approximation of the one band Hubbard model, we discuss the origin of the changing Fermi surface volume in underdoped cuprate systems due to the tran…
Theory for the Nonlinear Ultrafast Dynamics of Small Clusters after Ionization
M. E. Garcia, D. Reichardt, K. H. Bennemann
The ultrafast relaxation of small clusters immediately after ionization is studied. For small Hg clusters we determine the fragmentation-time distributions induced by ionizatio…
Electronic Theory for Bilayer-Effects in High-T_c Superconductors
S. Grabowski, J. Schmalian, M. Langer +1
The normal and the superconducting state of two coupled CuO_2 layers in the High-T_c superconductors are investigated by using the bilayer Hubbard model, the FLEX approximation on…
Theory for the Dependence of Optical Second Harmonic Generation Intensity on Non-equilibrium Electron Temperatures at Metal Surfaces
T. A. Luce, W. Huebner, K. H. Bennemann
We present a theory for the electron-temperature dependence of optical second harmonic generation (SHG). Such an analysis is required to study the dynamics of metallic sys…
