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…
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…
Connecting Pre-Thermal and Hydrodynamizing Attractors With Adiabatic Hydrodynamization
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Rachel Steinhorst
The far-from equilibrium dynamics of the pre-hydrodynamic quark-gluon plasma (QGP) formed in heavy ion collisions can be characterized by distinct stages, during each of which the…
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…
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…
