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…
Attractodynamics in 0+1D
Jean F. Du Plessis, Bruno Scheihing-Hitschfeld, Rachel Steinhorst
Hydrodynamics is a macroscopic theory of long-wavelength dynamics around local thermal equilibrium. We develop attractodynamics, the analogous construction around a far-from-equili…
Stochastic Dynamics of Heavy Quarks in Strongly Coupled Plasma
Krishna Rajagopal, Bruno Scheihing-Hitschfeld, Urs Achim Wiedemann
We study the stochastic dynamics of heavy quarks propagating through the strongly coupled plasma of supersymmetric Yang-Mills (SYM) theory at nonzero temperature in…
Heavy Quark Transport is Non-Gaussian Beyond Leading Log
Jean F. Du Plessis, Bruno Scheihing-Hitschfeld
We find that heavy quark transport beyond leading logarithm at weak coupling is intrinsically non-Gaussian: the longitudinal momentum transfer distribution has asymmetric exponenti…
Quantum and Thermal Fluctuations of Cherenkov Radiation from HQET
Joshua Lin, Bruno Scheihing-Hitschfeld
Charged particles travelling faster than the speed of light in the medium in which they propagate emit Cherenkov radiation. The formula for the spectrum of this radiation as a func…
Quantum tunneling from excited states in the steadyon picture
Joshua Lin, Bruno Scheihing-Hitschfeld, Thomas Steingasser
Recent developments in the understanding of real-time path integrals led to the development of the ``steadyon picture'' for the semi-classical calculation of quantum tunneling rate…
