Extended theory of finite Fermi systems: Application to the collective and noncollective E1 strength in Pb208
Victor Tselyaev,Victor Tselyaev,J. Speth,F. Grümmer,S. Krewald,A. Avdeenkov,Elena Litvinova,G. Tertychny +7 more
TL;DR: 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.

Pygmy dipole resonance in stable Ca isotopes
G. Tertychny,V. Tselyaev,Sergei Kamerdzhiev,F. Grümmer,S. Krewald,J. Speth,Elena Litvinova,A. Avdeenkov +7 more
TL;DR: In this paper, the properties of low-lying electric dipole strength in the stable 40 Ca, 44 Ca and 48 Ca isotopes have been calculated within the Extended Theory of Finite Fermi Systems (ETFFS).

Self-consistent calculations within the Green’s function method including particle-phonon coupling and the single-particle continuum
TL;DR: In this article, the Green's function in the Quasiparticle Time Blocking Approximation is applied to nuclear excitations in 132Sn and 208Pb and the calculations are performed self-consistently using a Skyrme interaction.

G. Tertychny,Victor Tselyaev,Victor Tselyaev,Sergei Kamerdzhiev,F. Grümmer,S. Krewald,J. Speth,A. Avdeenkov,Elena Litvinova +8 more
TL;DR: In this paper, the properties of low lying and high lying electric dipole strength in the stable 40Ca, 44Ca and 48Ca isotopes have been calculated within the Extended Theory of Finite Fermi Systems (ETFFS).
Self-consistent calculations within the extended theory of finite Fermi systems
A. Avdeenkov,F. Grümmer,Sergei Kamerdzhiev,S. Krewald,N. Lyutorovich,N. Lyutorovich,J. Speth +6 more
TL;DR: In this paper, the authors employ the nuclear mean field derived from Skyrme interactions and the corresponding particle-hole interaction to describe the spreading widths of the giant resonances in the new approach, but produce shifts of the centroid energies.
