Symmetry and localization properties of defect modes in magnonic superlattices
Rodolfo A. Gallardo, Tobias Schneider, Alejandro Roldán-Molina +5
Symmetry and localization properties of defect modes of a one-dimensional bi-component magnonic superlattice are theoretically studied. The magnonic superlattice can be seen as a p…
The role of the internal demagnetizing field in a surface-modulated magnonic crystal
Manuel Langer, Falk Röder, Rodolfo A. Gallardo +9
Magnonic crystals with locally alternating properties and specific periodicities exhibit interesting effects, such as a multitude of different spin-wave states and large band gaps.…
Spin-wave spectra in periodically surface-modulated ferromagnetic thin films
R. A. Gallardo, M. Langer, A. Roldán-Molina +4
This article presents theoretical results for the dynamic response of periodically surface-modulated ferromagnetic thin films. For such system, the role of the periodic dipolar fie…
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 Doping Dependence of Spin Fluctuation Induced Shadow States in High-T Superconductors
M. Langer, J. Schmalian, S. Grabowski +1
We analyze the doping dependence of the intensity and energetical position of shadow states in high -T superconductors within the 2D Hubbard model and using our recently deve…
Theory for Superconducting Properties of the Cuprates: Doping Dependence of the Electronic Excitations and Shadow States
S. Grabowski, M. Langer, J. Schmalian +1
The superconducting phase of the 2D one-band Hubbard model is studied within the FLEX approximation and by using an Eliashberg theory. We investigate the doping dependence of …
Electronic Theory for the Transition from Fermi-Liquid to Non-Fermi-Liquid Behavior in High-T Superconductors
M. Langer, J. Schmalian, S. Grabowski +1
We analyze the breakdown of Fermi-liquid behavior within the 2D Hubbard model as function of doping using our recently developed numerical method for the self consistent summation…
Theory for the Interdependence of High-T Superconductivity and Dynamical Spin Fluctuations
S. Grabowski, J. Schmalian, M. Langer +1
The doping dependence of the superconducting state for the 2D one-band Hubbard Hamiltonian is determined. By using an Eliashberg-type theory, we find that the gap function $Δ_{\bf…
