abstract
The success of hydrodynamics in high energy heavy-ion collisions leads to a flow paradigm, to understand the observed features of harmonic flow in terms of the medium collective expansion regarding initial state geometrical properties. In this review, we present some essential ingredients in the flow paradigm, including the hydrodynamic modeling, the characterization of initial state geometry and the medium response relations. The extension of the flow paradigm to small colliding systems is also discussed.

Coherent State Path Integral Reveals Unexpected Vacuum Structure in Thermal Field Theory
A coherent-state derivation of the thermal partition function yields extra vacuum and mass-coupling terms that the authors claim are novel, though these terms reflect the chosen operator ordering.
