Imaging non-hydrodynamic modes with jet wakes
Aleksi Kurkela, Ian Moult, Alexander Soloviev +1
While studies of ultra-relativistic heavy-ion collisions have established that the quark--gluon plasma exhibits hydrodynamic behavior, direct signatures of non-hydrodynamic modes h…
Machine learning approach to QCD kinetic theory
Sergio Barrera Cabodevila, Aleksi Kurkela, Florian Lindenbauer
The effective kinetic theory (EKT) of QCD provides a possible picture of various non-equilibrium processes in heavy- and light-ion collisions. While there have been substantial adv…
Updated Astrophysical Equation-of-State Constraints on the Color-Superconducting Gap
Aleksi Kurkela, Krishna Rajagopal, Rachel Steinhorst
We summarize and update using new NICER measurements the results of arXiv:2401.16253, in which we used various astrophysical neutron-star observations to set an upper bound on the…
Solving the QCD effective kinetic theory with neural networks
Sergio Barrera Cabodevila, Aleksi Kurkela, Florian Lindenbauer
Event-by-event QCD kinetic theory simulations are hindered by the large numerical cost of evaluating the high-dimensional collision integral in the Boltzmann equation. In this work…
Estimate for the bulk viscosity of strongly coupled quark matter using perturbative QCD and holography
Jesús Cruz Rojas, Tyler Gorda, Carlos Hoyos +6
Modern hydrodynamic simulations of core-collapse supernovae and neutron-star mergers require knowledge not only of the equilibrium properties of strongly interacting matter, but al…
Limiting attractors in heavy-ion collisions -- the interplay between bottom-up and hydrodynamic attractors
Kirill Boguslavski, Aleksi Kurkela, Tuomas Lappi +2
In this contribution to the Quark Matter 2023 proceedings, we study the hydrodynamization process in heavy-ion collisions using QCD kinetic theory and introduce the new concept of…
