Query: Nuclear Shell Structure in a Finite-Temperature Relativistic Framework   The shell evolution of neutron-rich nuclei with temperature is studied in a
beyond-mean-field framework rooted in the meson-nucleon Lagrangian. The
temperature-dependent Dyson equation with the dynamical kernel taking into
account the particle-vibration coupling (PVC) is solved for the fermionic
propagators in the basis of the thermal relativistic mean-field Dirac spinors.
The calculations are performed for $^{68-78}$Ni in a broad range of
temperatures $0 \leq T \leq 4$ MeV. The special focus is put on the
fragmentation pattern of the single-particle states, which is further
investigated within toy models in strongly truncated model spaces. Such models
allow for quantifying the sensitivity of the fragmentation to the phonon
frequencies, the PVC strength and to the mean-field level density. The model
studies provide insights into the temperature evolution of the PVC mechanism in
real nuclear systems under the conditions which may occur in astrophysical
environments.
