Recent results on flow and correlations from the ATLAS experiment

The azimuthal anisotropy in Xe+Xe collisions at the energy of $\sqrt{s_{\rm NN}}$ = 5.44 TeV was recently investigated in the ATLAS experiment at the LHC. Preliminary results on the $p_{\rm T}$ and centrality dependence of $v_{\rm 2}$ and $v_{\rm 3}$ harmonics obtained with multi-particle cumulants are presented. The measurements indicate a presence of nearly Gaussian $v_{\rm n}$ harmonic fluctuations in the Xe+Xe system. For Pb+Pb collisions at the energy of $\sqrt{s_{\rm NN}}$ = 2.76 and 5.02 TeV the longitudinal flow harmonic correlations are presented, providing evidence that the correlations between separated in pseudorapidity $v_{\rm n}$ (n=2--4) do not factorise into the product of single-particle $v_{\rm n}$. Additionally, for Pb+Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV, a preliminary determination of the modified Pearson's correlation coefficient for the event-wise mean transverse momentum and $v_{\rm n}^2$ (n=2-4) is shown. Significant, non-zero correlation coefficients are measured for all $v_{\rm n}$ harmonics.
