Abstract: In the past two decades, relativistic nuclear collisions have significantly expanded the boundary of our knowledge about phases of matter into previously uncharted territory. Such experiments at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), spanning three orders of magnitude in collisional beam energies from GeV to TeV range, have opened novel dimensions for exploring QCD matter. In this talk, three examples will be discussed. In the O(1~10) GeV beam energy region, the produced hot dense matter is found to behave as the most vortical fluid whose macroscopic motion polarizes the quantum spin of its microscopic constituents. In the O(~100) GeV region, the hot quark gluon plasma turns out to be a chiral material that makes it possible to observe a nontrivial anomalous transport phenomenon called the chiral magnetic effect, which has attracted substantial multidisciplinary interests. In the O(~1000) GeV region, the collisions are so violent that they create a richly “doped” QGP embedding an unparalleled abundance of charm flavor. This offers a unique environment for the massive production of exotic hadrons in nuclear collisions and possibly helps deciphering the puzzles concerning their intrinsic structures, as shown by the latest theoretical studies and experimental measurements.
