We review the phenomenology and theory of bulk observables in ultra-relativistic heavy-ion collisions, focusing on recent developments involving event-by-event fluctuations in the initial stages of a heavy-ion collision, and how they manifest in observed correlations. We first define the relevant observables and show how each measurement is related to underlying theoretical quantities. Then we review the prevailing picture of the various stages of a collision, including the state-of-the-art… 
Correlations in the Initial Conditions of Heavy-Ion Collisions
Ultracentral collisions of heavy nuclei, in which the impact parameter is nearly zero, are especially sensitive to the details of the initial state model and the microscopic mechanism for collective
Fluctuations in ultra-relativistic heavy ion collisions
Fluctuations are one of the main probes of the physics of the new state of hot and dense nuclear matter called the Quark Gluon Plasma (QGP) which is created in the ultra-relativistic heavy ion
The influence of initial state fluctuations on heavy quark energy loss in relativistic heavy-ion collisions
We study the effects of initial state fluctuations on the dynamical evolution of heavy quarks inside a quark–gluon plasma (QGP) created in relativistic heavy-ion collisions. The evolution of heavy
Model comparison for initial density fluctuations in high-energy heavy-ion collisions
Four models for the initial conditions of a fluid dynamic description of high energy heavy ion collisions are analysed and compared. We study expectation values and event-by-event fluctuations in the
Approach to equilibrium in high energy heavy ion collisions
This thesis deals with the theory of the early stages of a heavy ion collision. Just after such a collision, the matter produced -- called the Quark-Gluon-Plasma (QGP) -- has been shown to be far out
Initial conditions for heavy ion collisions with QCD kinetic theory
We employ the leading order QCD kinetic theory to describe a consistent matching between the initial stage of a heavy ion collision and the subsequent hydrodynamic evolution. We use the linearized
Matching the Nonequilibrium Initial Stage of Heavy Ion Collisions to Hydrodynamics with QCD Kinetic Theory.
TLDR
A framework using nonequilibrium Green's functions, calculated in QCD kinetic theory, to propagate the initial energy-momentum tensor to the hydrodynamic phase is built, leading to stronger constraints on the energy density at early times and the transport properties of the QCD medium.
Observables for longitudinal flow correlations in heavy-ion collisions
We propose several new observables/correlators, based on correlations between two or more subevents separated in pseudorapidity $\eta$, to study the longitudinal flow fluctuations. We show that these
Study of Jet Modification in Relativistic Heavy-Ion Collisions
The study of jets, algorithmic representations of collimated sprays of particles, in relativistic heavy-ion collisions can illuminate the underlying physics of heavy ion experiments, as the ones in

TLDR
Recent developments aimed at understanding whether, and if so how, systems that produce relatively few particles and are only one to a few times the size of a proton, can behave like fluids are described.
