Functional Renormalization Group flows as diffusive Hamilton-Jacobi-type equations
Adrian Koenigstein, Martin J. Steil, Stefan Floerchinger
In order to find reliable and efficient numerical approximation schemes, we suggest to identify the Functional Renormalization Group flow equations of one-particle irreducible two-…
Shear viscosity of a relativistic scalar field from functional renormalization
Tim Stoetzel, Stefan Floerchinger
Renormalization group flow equations of the fluid dynamical shear viscosity transport coefficient of a relativistic real scalar field are derived. The flowing effective action cont…
Evidence for dynamical chiral condensate in high-energy heavy ion collisions
Tobias Bruschke, Andreas Kirchner, Stefan Floerchinger
Quantum chromodynamics with light quarks features an approximate global symmetry, known as chiral symmetry, that is believed to be spontaneously broken by the vacuum expectation va…
Fluid dynamics of charm quarks from heavy to light-ion collisions
Federica Capellino, Andrea Dubla, Rossana Facen +3
Heavy quarks are powerful tools to characterize the quark-gluon plasma (QGP) produced in relativistic nuclear collisions. By exploiting a mapping between transport theory and hydro…
Energy-momentum response to metric perturbations in the fluid dynamic regime
Tim Stoetzel, Rebekka Fechtner, Stefan Floerchinger
The interplay of relativistic fluid dynamics and spacetime geometry is discussed in the regime of small wave numbers and frequencies. A combination of gravitational Ward identities…
