What we are working on: We are working on the theoretical studies of relativistic heavy ion collisions.

In order to understand the asymptotic freedom in strong interactions (also see 2004 Nobel Prize in Physics), T.D Lee (李政道, 1974) and Collins (1975) proposed to use the relativistic heavy ion collisions to creat a new form of matter, Quark-Gluon Plasma (QGP).

Very high magnetic fields and orbital angular momenta (OAMs) are generated in these collisions. The magnetic fields are on the order of 10^(17−18) Gauss and are the strongest magnetic fields observed in nature. The QGP is also found to be the most vortical fluid, where a huge OAM is transferred to the fluid in the form of vorticity fields. These novel phenomena open a new window for the study of the QGP in heavy-ion collisions. These novel phenomena are quantum in nature and are usually negligible in classical fluids.
