Spin relaxation of heavy quarks from momentum diffusion in the quark-gluon plasma
Ankit Kumar, Sourav Dey, Vinod Chandra +1
Heavy-quark spin dynamics in the quark-gluon plasma provides a potential probe of the interaction between heavy quarks and the medium. We develop a stochastic framework in which th…
Spin dynamics and polarization in relativistic systems: recent developments
Sourav Dey, Arpan Das, Hiranmaya Mishra +1
We review recent theoretical and experimental developments in spin dynamics and polarization phenomena in relativistic systems, with a particular focus on heavy-ion collisions. The…
Quantum spin dynamics of heavy quarks and polarization observables in relativistic heavy-ion collisions
Sunil Jaiswal, Sourav Dey, Amaresh Jaiswal
We develop a quantum spin-density-matrix framework for heavy-quark spin dynamics in relativistic heavy-ion collisions. Starting from an initial polarization induced along the magne…
Dissipative spin hydrodynamics in Bjorken flow and thermal dilepton production
Sejal Singh, Sourav Dey, Arpan Das +2
We investigate the boost-invariant expansion of a recently developed first-order spin hydrodynamic framework in which the spin chemical potential is treated as a leading-order hydr…
