vn. We find that the common practice of using an r 2 weight in the definition of "n in general results in a poorer predictor of vn than when using r n weight, for n > 2. We similarly study the importance of additional properties of the initial state. For example, we show that in order to correctly predict v4 and v5 for non-central collisions, one must take into account nonlinear terms proportional to " 2 and "2"3, respectively. We find that it makes no difference whether one calculates the…

Statistics of initial density perturbations in heavy ion collisions and their fluid dynamic response
A bstractAn interesting opportunity to determine thermodynamic and transport properties in more detail is to identify generic statistical properties of initial density perturbations. Here we study
Subleading harmonic flows in hydrodynamic simulations of heavy ion collisions
We perform a principal component analysis (PCA) of $v_3(p_T)$ in event-by-event hydrodynamic simulations of Pb+Pb collisions at the Large Hadron Collider (LHC). The PCA procedure identifies two
On nonlinearity in hydrodynamic response to the initial geometry in relativistic heavy-ion collisions
In the context of event-by-event hydrodynamic description, we analyze the implications of two models characterized by distinct initial conditions. The initial energy density of the first model adopts
Understanding non-linear hydrodynamic response in heavy-ion collisions via event-plane correlations
Recently the ATLAS collaboration measured correlations between pairs and triplets of event-plane angles in Pb+Pb collisions at =2.76 TeV and observed interesting centrality dependent patterns. In
Initial conditions of bulk matter in ultrarelativistic nuclear collisions
Dynamical models based on relativistic fluid dynamics provide a powerful tool to extract the properties of the strongly-coupled quark-gluon plasma (QGP) produced by ultrarelativistic nuclear
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
