Migdal and his theory in Jülich
J. Speth, F. Grümmer, S. Krewald
We review the application of Migdal's "Theory of Finite Fermi System" to the structure of deformed nuclei, approaches beyond the conventional linear response, and microscopic calcu…
Self-consistent calculations within the Green's function method including particle-phonon coupling and the single-particle continuum
N. Lyutorovich, J. Speth, A. Avdeenkov +4
The Green's function method in the \emph{Quasiparticle Time Blocking Approximation} is applied to nuclear excitations in Sn and Pb. The calculations are performed s…
Extended Theory of Finite Fermi Systems: Application to the collective and non-collective E1 strength in Pb
V. Tselyaev, J. Speth, F. Gruemmer +4
The Extended Theory of Finite Fermi Systems is based on the conventional Landau-Migdal theory and includes the coupling to the low-lying phonons in a consistent way. The phonons gi…
Microscopic description of the pygmy and giant electric dipole resonances in stable Ca isotopes
G. Tertychny, V. Tselyaev, S. Kamerdzhiev +5
The properties of the pygmy (PDR) and giant dipole resonance (GDR)in the stable , and isotopes have been calculated within the \emph{Extended Theory of…
Prediction oriented variant of financial log-periodicity and speculating about the stock market development until 2010
S. Drozdz, F. Gruemmer, F. Ruf +1
A phenomenon of the financial log-periodicity is discussed and the characteristics that amplify its predictive potential are elaborated. The principal one is self-similarity that o…
