Analytic structure of nonhydrodynamic modes in kinetic theory
Aleksi Kurkela, Urs Achim Wiedemann
How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mec…
Gravitational-wave constraints on the neutron-star-matter Equation of State
Eemeli Annala, Tyler Gorda, Aleksi Kurkela +1
The LIGO/Virgo detection of gravitational waves originating from a neutron-star merger, GW170817, has recently provided new stringent limits on the tidal deformabilities of the sta…
Plasmon mass scale and quantum fluctuations of classical fields on a real time lattice
Tuomas Lappi, Aleksi Kurkela, Jarkko Peuron
Classical real-time lattice simulations play an important role in understanding non-equilibrium phenomena in gauge theories and are used in particular to model the prethermal evolu…
Initial conditions for hydrodynamics from kinetic theory equilibration
Aleksi Kurkela, Aleksas Mazeliauskas, Jean-François Paquet +2
We use effective kinetic theory to study the pre-equilibrium dynamics in heavy-ion collisions. We describe the evolution of linearized energy perturbations on top of out-of-equilib…
