In the early morning of 5 Oct. 2004, Professor Frank Wilczek of MIT was informed by phone from Stockholm of Sweden that he won the 2004 Nobel Prize in physics, together with David J. Gross of California University at Santa Barbara, and H. David Politzer of the California Institute of Technology. A press conference was immediately held at MIT in the morning, and a celebration reception was organized by the Department of Physics and the Center for Theoretical Physics in the afternoon. The former has been well reported by the media while the later is comparatively not so well-known to the public. Being a visiting scientist at the MIT-CTP, I was lucky to participate in the reception. The pictures here record this great moment of the scientific community.

1. Properties of quark matter and mechnism of QCD phase transition (Grant No. 11135011)
Quark matter is a new form of matter predicted by QCD. It can either exist in the inner part of compact stars, or be created in heavy ion collisions. In this project, we study the structure of compact stars (neutron stars, quark stars etc.) to explore the properties of quark matter at lower temperature. At the same time, we study the detail process of heavy ion collisions to understand the properties of quark matter at high temperature (quark-gluon plasma). Then we investigate the full structure of QCD, and link them to several frontiers in modern nuclear physics, such as chiral condensates, deconfinement phase transition, multi-quark states, color superconductivity, and nuclear symmetry energy etc. to further understand the mechanism of QCD phase transition. Theoretically we develop quark-confinement models, establish more efficient parton-dynamics models for heavy ion collisions, explore applications of AdS/CFT in quark matter-related areas; experimentally, we search for the signature of QCD phase transition and critical regions. We limit model parameters by using data from both astronomical observations and heavy-ion experiments to make our theoretical results in better agreement with experiments. We hope to push forward the study of both compact stars and heavy-ion physics, and deepen the understanding of the law of strong interactions and the new forms of matter.
2. QCD phase structure and properties of pulsars (No. 11875052)
Pulsars are an ideal laboratory to study the form and properties of strongly interacting matter due to the high inner density and rich astronomical observational data. This project investigates the phase structure of strongly interacting matter, including the matter from, phase boundaries, and critical points of the phase diagram in the temperature-density-isospin space, and the application to structure and properties of pulsars. Specially, we concentrate on the frontier problems in modern nuclear physics relevant to quark matter, such as the constituent-matter form, mass-radius relation, macroscopic properties of millisecond massive pulsars, deconfinement and chiral restoration phase transitions, the formation and evolution of quark-gluon plasma in high-energy heavy-ion collisions, and the production possibility and detection signals of strangelets in the isentropic process etc. We expect to deepen the investigation of strongly interacting matter and the knowledge of new-form mater.
