Non-Gaussian fluctuation dynamics in relativistic fluids
Xin An, Gokce Basar, Mikhail Stephanov +1
We consider non-equilibrium evolution of non-Gaussian fluctuations within relativistic hydrodynamics relevant for the QCD critical point search in heavy-ion collision experiments.…
Spin relaxation rate for heavy quarks in weakly coupled QCD plasma
Masaru Hongo, Xu-Guang Huang, Matthias Kaminski +2
We compute the relaxation rate of the spin density of heavy quarks in a perturbative QCD plasma to leading-log order in the coupling constant . The spin relaxation rate in…
Relativistic spin hydrodynamics with torsion and linear response theory for spin relaxation
Masaru Hongo, Xu-Guang Huang, Matthias Kaminski +2
Using the second law of local thermodynamics and the first-order Palatini formalism, we formulate relativistic spin hydrodynamics for quantum field theories with Dirac fermions, su…
Non-dissipative second-order transport, spin, and pseudo-gauge transformations in hydrodynamics
Shiyong Li, Mikhail A. Stephanov, Ho-Ung Yee
We derive a set of nontrivial relations between second-order transport coefficients which follow from the second law of thermodynamics upon considering a regime close to uniform ro…
Evolution of Non-Gaussian Hydrodynamic Fluctuations
Xin An, Gokce Basar, Mikhail Stephanov +1
In the context of the search for the QCD critical point using non-Gaussian fluctuations, we obtain the evolution equations for non-Gaussian cumulants to the leading order of the sy…
Fluctuation dynamics in a relativistic fluid with a critical point
Xin An, Gokce Basar, Mikhail Stephanov +1
To describe dynamics of bulk and fluctuations near the QCD critical point we develop general relativistic fluctuation formalism for a fluid carrying baryon charge. Feedback of fluc…
