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.
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

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.


Initial state fluctuations and final state correlations: status and open questions
The recent appreciation of the importance of event-by-event fluctuations in relativistic heavy-ion collisions has lead to a large amount of diverse theoretical and experimental activity. In
A systematic study of the sensitivity of triangular flow to the initial state fluctuations in relativistic heavy-ion collisions
Experimental data from the Relativistic Heavy-Ion Collider suggest that the quark gluon plasma behaves almost like an ideal fluid. Due to its short lifetime, many QGP properties can only be inferred
Relativistic theory of hydrodynamic fluctuations with applications to heavy-ion collisions
We develop the relativistic theory of hydrodynamic fluctuations for application to high-energy heavy-ion collisions. In particular, we investigate their effect on the expanding boost-invariant
Determining initial-state fluctuations from flow measurements in heavy-ion collisions
We present a number of independent flow observables that can be measured using multiparticle azimuthal correlations in heavy-ion collisions. Some of these observables are already well known, such as
Energy loss in a fluctuating hydrodynamical background
Recently it has become apparent that event-by-event fluctuations in the initial state of hydrodynamical modelling of ultrarelativistic heavy-ion collisions are crucial in order to understand the full
Collective dynamics in high-energy proton-nucleus collisions
We analyze the proton-lead collisions at the CERN Large Hadron Collider energy of sNN=5.02 TeV in the three-stage approach, previously used to successfully describe the relativistic A-A collisions.
Initial state anisotropies and their uncertainties in ultrarelativistic heavy-ion collisions from the Monte Carlo Glauber model
In hydrodynamical modeling of heavy-ion collisions, the initial-state spatial anisotropies are translated into momentum anisotropies of the final-state particle distributions. Thus, understanding the

We study how local fluctuations in the initial states of relativistic heavy-ion collisions manifest themselves in the correlations between different orders of harmonic moments of the density
