Extended theory of finite Fermi systems: collective vibrations in closed shell nuclei

S Kamerdzhiev, J Speth, G Tertychny - Physics reports, 2004 - Elsevier
We review an extension of Migdal's Theory of Finite Fermi Systems which has been
developed and applied to collective vibrations in closed shell nuclei in the past 10 years …

Nuclear ground-state properties from mean-field calculations

J Dobaczewski, W Nazarewicz, MV Stoitsov - Exotic Nuclei and Atomic …, 2003 - Springer
The volume and surface effects in the nuclear local energy density and the volume and
surface components of the pairing interaction are discussed in the context of the mean-field …

On the dynamical kernels of fermionic equations of motion in strongly-correlated media

E Litvinova - The European Physical Journal A, 2023 - Springer
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 …

Many-body theory for quasiparticle states in superfluid fermionic systems

E Litvinova, Y Zhang - Physical Review C, 2021 - APS
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 …

Continuum particle-vibration coupling method in coordinate-space representation for finite nuclei

K Mizuyama, G Coló, E Vigezzi - Physical Review C—Nuclear Physics, 2012 - APS
In this paper we present a new formalism to implement the nuclear particle-vibration
coupling (PVC) model. The key issue is the proper treatment of the continuum that is allowed …

Many-body correlations in nuclear superfluidity

E Litvinova, P Schuck - Physical Review C, 2020 - APS
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 …

Mean-field and pairing properties of exotic nuclei: Exploring the nuclear landscape

J Dobaczewski, W Nazarewicz - Progress of Theoretical Physics …, 2002 - academic.oup.com
In years to come, we shall see substantial progress in our understanding of nuclear structure–
a rich and many-faceted field. An important element in this task will be to extend the study of …

Interaction of the single-particle and collective degrees of freedom in non-magic nuclei: The role of phonon tadpole terms

S Kamerdzhiev, EE Saperstein - The European Physical Journal A, 2008 - Springer
A method of consistent treatment of phonon contributions to the self-energy and gap terms in
non-magic nuclei is developed in so-called g 2 approximation, where g is the creation …

Nuclear superfluidity at finite temperature

E Litvinova, P Schuck - Physical Review C, 2021 - APS
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 …
