Abstract
In the last year we continued to work on various aspects of statistical physics, high energy and
condensed matter physics. We kept sharing common interests in the study of
unusual and exotic phases of matter, and the related phase transitions.
Our Iniziativa Specifica (IS) offers a natural ground
for discussions of these phenomena.
Before entering into the details of the scientific achievements
of the last year, let us highlight how cross-fertilization plays a central role
in quantum field theory and critical phenomena
by using some examples (out of many more) from our work.
First, consider the crucial issue of the nature
of the thermal transition in QCD (Pisa and Roma with RG, Torino within
effective string models, LNF numerically).
This is, in turn, deeply entangled with the fate of the chiral anomaly at the transition (Pisa),
and it is ultimately related with the behaviour of systems at high density (Milano
and LNF). As a second example, consider the recent developments
in four dimensional conformal field theories (LNF), with their potential applications to physics beyond the standard model, where the expertise gained in lower dimensionalities and integrable models is crucial (Torino, Pisa, Roma).
Finally, condensation phenomena were for many years a typical condensed matter subject, but
are now playing a central role also in high energy physics, in the dense phases
of matter which are relevant for neutron stars (Milano and Pisa), and other branches
of theoretical physics.
