"Quantum chaos and
thermalization in a small isolated system of interacting particles"

Vladimir
Zelevinsky

Michigan State University, USA

*Abstract:* Atomic nuclei belong to the class of
mesoscopic quantum systems with strong interaction between constituents.
In mesoscopic systems, the presence of statistical features coexists with
the opportunities to study, theoretically and experimentally, individual
quantum states. Statistical aspects include chaotic regularities of
spectra, wave functions and reaction amplitudes, leading to thermalization
without any external heat bath. Strong interactions mix simple particle
states creating complicated manybody functions with characteristic
signatures of quantum chaos. This allows to treat the system statistically
using thermodynamic concepts and obtain physical results avoiding the
diagonalization of prohibitively huge Hamiltonian matrices. The variation
of the Hamiltonian displays the special role of certain matrix elements
responsible for collective phenomena on the background of chaos driven by
numerous collision-like interactions. Some theoretical problems are still
waiting for their solution.

**"Study
of Short Range Correlations via the A(e,e'n) reaction"**

Meytal Duer

Tel Aviv University

*Abstract:* Without short range interaction, the
Pauli exclusion principle causes the majority nucleons (usually neutrons)
in an asymmetric nucleus to have higher average momentum than the
minority. High-energy electron scattering
measurements showed that the short range interaction between the nucleons
mainly form correlated high momentum
neutron-proton pairs in the nucleus. Thus, in neutron-rich nuclei, protons
have greater probability than neutrons
to have momentum larger than the Fermi momentum. Based on our new data
from CLAS at Jefferson Laboratory
we claim that this results in protons having higher average momentum than
neutrons, i.e., an inversion of the
momentum sharing between majority and minority nucleons.
