Flow decorrelations in 5.44 TeV Xe+Xe collisions in ATLAS / Behera, Arabinda (Stony Brook University) /ATLAS Collaboration
Longitudinal decorrelations of harmonic flow $v_n$ is measured for Xe+Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44$ TeV using the ATLAS detector at the LHC. The decorrelation signal for $v_3$ and $v_4$ is found to be nearly independent of centrality percentiles and transverse momentum ($p_{\mathrm{T}}$), but has strong centrality and $p_{\mathrm{T}}$ dependence for $v_2$.

Measurement of suppression of large-radius jets and its dependence on substructure in Pb+Pb at 5.02 TeV with ATLAS / Zou, Wenkai (Nevis Laboratory, Columbia University) /ATLAS Collaboration
Measurements of the jet substructure in Pb+Pb collisions provide information on the jet quenching in the quark-gluon plasma (QGP) created in these collisions, over a wide range of energy scales. This poster presents ATLAS measurement of the suppression of yields of large-radius jets and its dependence on the jet substructure, characterized by the presence of sub-jets and their angular correlations.

Correlation of flow harmonics and mean transverse momentum 
in 5.02 TeV p+Pb and Pb+Pb collisions 
and event-plane dependence of HBT radii in high-multiplicity p+Pb collisions with the ATLAS detector / Bold, Tomasz (AGH University of Science and Technology, Faculty of Physics and Applied Computer Science, Krakow) /ATLAS Collaboration
To assess the properties of the quark-gluon plasma formed in heavy ion collisions, correlations between the mean transverse momentum, [$p_{T}$], and the magnitude of the flow harmonics, $v_{n}$, are measured by the ATLAS experiment at the LHC.Ê The analysis uses data samples of lead-lead collisions at $\sqrt{s_{NN}} =5.02$~TeV and proton-lead collisions at $\sqrt{s_{NN}} =5.02$~TeV, corresponding to integrated luminosities of 22 $\mu$b$^{-1}$ and 28 nb$^{-1}$, respectively. The correlations are measured using a modified Pearson coefficient that is independent of multiplicity fluctuations. [...]

Measurement of jet structure and substructure in heavy ion collisions with ATLAS / Rybar, Martin (Nevis Laboratory, Columbia University) /ATLAS Collaboration
Studies of jet structure in heavy-ion collisions can provide information about the mechanism of jet quenching in the hot and dense QCD medium created in these collisions. This talk presents the latest ATLAS measurement of the internal structure of jets to shed more light on the modification of the parton showering process in the presence of the medium. [...]

ATLAS measurements of transverse and longitudinal flow fluctuations in Pb+Pb and Xe+Xe collisions / Mohapatra, Soumya (Nevis Laboratory, Columbia University) /ATLAS Collaboration
ATLAS measurements of flow harmonics ($v_n$) and their fluctuations in Pb+Pb and Xe+Xe collisions covering a wide range of transverse momenta, pseudorapidity and collision centrality are presented. The $v_n$ are measured up to $n=7$ using the two-particle correlations, multi-particle cumulants and scalar product methods.The $v_n$ for $n$=2-7 is obtained with various correlation methods, together with a non-flow subtraction technique to improve the understanding of flow in peripheral region.A universal scaling in the $p_T$ dependence of the

In ultra-relativistic heavy-ion collisions, one expects copious rates of γ + γ processes through the interaction of the large electromagnetic fields of the nuclei, which can produce new particles (e.g. leptons) or even lead to light-by-light scattering via loop diagrams. [...]
