## Frontiera E Confini Della Fisica Di Molte ParticelleR. A. Broglia, John Robert Schrieffer, Società italiana di fisica Subjects at the forefront of many-particle research, like high-temperature superconductivity, the quantum Hall effect, heavy fermions, tunneling of quantal systems with many degrees of freedom, Monte Carlo calculations on a lattice etc., were presented. The meeting was well timed as it coincided with a very active period of research in the study of superconductivity and thus provided an excellent opportunity to assess some of the major developments that have taken place in the last years. |
