نویسنده
چکیده
We show that the collective vibrational model of atomic nuclei displays quantum chaos. To avoid the problems related to the tunneling effects, a Green function deterministic numerical method has been used to evaluate the energy levels.

The presence of chaos and quantum chaos is shown in two different nuclear systems. We analyze the chaotic behaviour of the classical SU(2) Yang–Mills– Higgs system, and then we study quantum chaos in the nuclear shell model calculating the spectral statistics of A = 46–50 atomic nuclei.

Using a classical analytical criterion (that of curvature) and numerical results (Poincarè sections and spectral statistics), a transition order–chaos– order in the roto–vibrational model of atomic nuclei has been shown. Numerical calculations were performed for some deformed nuclei.

We argue that current data on nuclear shadowing confirm expectations of the color singlet models of nuclear shadowing. We demonstrate that unitarity constrains require nuclear shadowing for gluons to be very significant already for x ≤ 10 . Physics of coherent diffraction production of vector mesons off light nuclei is also discussed.

The optimized δ-expansion is used to study vacuum polarization effects in the Walecka model. The optimized δ-expansion is a nonperturbative approach for field theoretic models which combines the techniques of perturbation theory and the variational principle. Vacuum effects on self-energies and the energy density of nuclear matter are studied up to O(δ 2). When exchange diagrams are neglected, ...
