The proposed program is about physics of matter of strong interaction under extreme conditions in high temperature and density. This situation was realized in the very early stages of the universe evolution and exists in the inner core of cold neutron stars and pure quark stars. In the laboratory, extreme conditions of temperature and density are created in heavy-ion collisions at relativistic energies. Such experiments are performed at the world's largest and most powerful accelerator facilities: the Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) and the Large Hadron Collider (LHC) at CERN. The ensuing “little bangs“ aim at creating similar conditions as those during the quark-hadron transition in the early universe, trying to advance our understanding of primordial strong interaction matter created in the “big bang”. The physical understanding of the dynamics of strong-interaction matter in the early universe, in astrophysical scenarios, or in heavy-ion collisions, requires detailed theoretical studies of its equilibrium and non-equilibrium properties. Central questions concern the phase diagram and the nature of possible phase transitions, the structure and fundamental degrees of freedom of the various phases, the pertinent transport properties and the thermalization time scale.

 
The last decade has witnessed several benchmark discoveries in this field – strongly coupled QGP (sQGP), jet quenching, collective flow, etc, which greatly deepen our understanding of strong interaction under extreme conditions. The sQGP is one of the most important discovery in relativistic heavy ion collisions in recent years. This sparks and initiate a number of new research directions and topics about sQGP properties in both experiments (RHIC, LHC etc.) and theories, many of them have made substantial progress.
 
There is a rapid growth of this field in China. The proposed program is aimed to bring together world-renowned theoretical physicists in this field and have deep discussions about fundamental properties of sQGP and extreme QCD among Chinese and abroad researchers. Most important is that the program will make a chance for young people in china to get in touch with world-class researchers and boost the generation of new ideas and new contacts.
