Probing Pair Correlations in QCD Matter with Photon Spectra
Xingjian Lu, Shuzhe Shi
Correlations in the phase-space distribution of partons play an important role in the initial stage of relativistic heavy-ion collisions, where the matter is dense and far from equ…
Thermal Spectra Without Detailed Balance
Xingjian Lu, Shuzhe Shi
A thermal spectrum is often taken as a signature that the emitted probe has reached detailed balance with the surrounding medium. We show that this interpretation is not generally…
Decoupling hydrodynamization from thermalization via nonlinear Boltzmann equation
Xingjian Lu, Shuzhe Shi
The early thermalization puzzle arises from the unexpectedly early applicability of hydrodynamics in heavy-ion collisions. While hydrodynamics has traditionally been associated wit…
Spectral BBGKY: a scalable scheme for nonlinear Boltzmann and correlation kinetics
Xingjian Lu, Shuzhe Shi
The Bogoliubov-Born-Green-Kirkwood-Yvon (BBGKY) hierarchy provides a time-reversal-symmetric framework for describing the nonequilibrium evolution of many-body systems. Despite the…
