The relativistic mean field (RMF) approach describing the motion of independent particles in
effective meson fields is extended by a microscopic theory of particle vibrational coupling. It …

Two-point fermionic propagators in strongly-correlated media are considered with an
emphasis on the dynamical interaction kernels of their equations of motion (EOM). With the …

For the first time, the shell structure of open-shell nuclei is described in a fully self-consistent
extension of the covariant energy density functional theory. The approach implies …

Background: Nuclear excited states within a wide range of excitation energies are formally
described by linear response theory. Besides its conventional formulation within the …

Within the framework of nuclear field theory (NFT), the spectrum of atomic nuclei is
described in terms of collective and quasiparticle degrees of freedom, that is, of elementary …

We present a formalism for the fermionic quasiparticle propagator in a superfluid fermionic
system. Starting from a general many-body Hamiltonian confined by the two-body …

The two-fermion two-time correlation function in the pairing channel is discussed within the
equation of motion framework. Starting from the bare two-fermion interaction, we derive the …

Background: Models based on using perturbative polarization corrections and mean-field
blocking approximation give conflicting results for masses of odd nuclei. Purpose: We …

We investigate the role the interweaving of surface vibrations and nucleon motion has on
Cooper pair formation in spherical superfluid nuclei. A quantitative calculation of the state …

The equation of motion for the two-fermion two-time correlation function in the pairing
channel is considered at finite temperature. Within the Matsubara formalism, the Dyson-type …
