Heavy quark transport in quark-gluon plasma beyond the non-relativistic limit
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Urs Achim Wiedemann
The dynamics of heavy quarks in quark-gluon plasma (QGP) formed in heavy ion collisions provide a unique window to characterize its properties. Existing approaches to describe heav…
Universal Equilibration Condition for Heavy Quarks
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Urs Achim Wiedemann
Kinetic equilibration at late times is physically required for heavy particles in a finite temperature medium. In Fokker-Planck dynamics, it is ensured by the Einstein relation bet…
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…
Dynamics of Heavy Quarks in Strongly Coupled SYM Plasma
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Urs Achim Wiedemann
We calculate the probability distribution for a heavy quark with velocity propagating through strongly coupled SYM plasma in the 't Hooft limit at…
Attractors Without Scaling: Adiabatic Hydrodynamization With and Without Inelastic Scattering
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Rachel Steinhorst
We study the process of hydrodynamization in kinetic theories of gluons undergoing boost-invariant expansion using the Adiabatic Hydrodynamization (AH) framework. We study both num…
Adiabatic Hydrodynamization and the Emergence of Attractors: a Unified Description of Hydrodynamization in Kinetic Theory
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Rachel Steinhorst
"Attractor" solutions for the pre-hydrodynamic, far-from-equilibrium, evolution of the matter produced in relativistic heavy ion collisions have emerged as crucial descriptors of t…
