In heavy ion collisions, the typical system size is large enough to be treated hydrodynamically but small enough for hydrodynamic fluctuations to be important and directly observable via event-by-event measurements. We present a general systematic formalism describing dynamics of fluctuations in an arbitrary relativistic hydrodynamic flow. We derive a deterministic evolution equation for the...

As a conserved quantity in the evolution of the quark-gluon plasma (QGP) created in heavy-ion collisions, the total angular momentum consists of two sectors: the orbital angular momentum (OAM) caused by kinetic motion, and the intrinsic spin angular momentum of quarks and gluons. In a heavy-ion collision event, the system starts with finite OAM but un-polarized spin density (unless prepared...

Nuclear structure functions and parton Wigner distributions of protons and nuclei are principal components of QCD phenomenology. Their first principle computation is an outstanding problem in QCD, because they involve non-perturbative nucleon/nuclear matrix elements of electromagnetic currents that are light-like separated in Minkowskian spacetime. Real-time correlation functions are a...

hydrodynamically, using the iEBE-VISHNU framework, and add the magnetic and electric fields as
well as the electric currents they generate in a perturbative fashion. We confirm the previously

A primary goal in heavy-ion collisions is to learn about non-equilibrium properties of the quark-gluon plasma (QGP), such as the size of its thermalization timescale and the values of its transport coefficients. Hard experimental probes like jets and heavy quarks, as well as photons [1], give direct access to these non-equilibrium properties. However, theoretical challenges have hindered...

The study of the QCD interaction at high temperature in the heavy quark (HQ) sector has attracted a wide interest in the last decade. The theoretical efforts to build realistic phenomenological models able to predict the main observables for D mesons, $R_{AA}$ and $v_2$, has lead to a first estimate of the Ds space diffusion of charm quarks. This has been a successful program that has allowed...
