Nuclear Response

We present some recent developments on the nuclear many-body problem, such as the treatment of high-order correlations and finite temperature in the description of in-medium two-nucleon propagators. In this work we discuss two-time propagators of the particle-hole type, which describe the response of finite nuclei to external probes without nucleon transfer. The general theory is formulated in terms of the equation of motion method for these propagators with the only input from the bare nucleon-nucleon interaction. The numerical implementation was performed on the basis of the effective mason-nucleon Lagrangian in order to study the energy-dependent kernels of different complexity. The finite-temperature extension of the theory with ph ⊗ phonon configurations is applied to a study of the multipole response of medium-mass nuclei.

We study the conductivity tensor for the pure anyon system at finite temperature by calculating the electromagnetic response function Kμν(ω, k) in the random-phase approximation. We find that the conductivity is indeed infinite through the vanishing of the renormalized Chern-Simons term for the statistical gauge fields in the limit k=0, ω→0. To study the Meissner effect at finite temperature, others have looked at Kµν(ω, k) in the limit ω=0, k→0. We compare the results and make some comments.
