Tricritical dynamics in - mixtures and QCD
Maneesha Pradeep, Johannes V. Roth, Lorenz von Smekal
In this paper we study the universal critical dynamics near the tricritical points in - mixtures and QCD with two massless quark flavors. In particula…
Universal scaling of transport coefficients near the liquid-gas critical point
Johannes V. Roth, Yunxin Ye, Sören Schlichting +1
We employ a novel real-time formulation of the functional renormalization group (FRG) to compute universal scaling functions of the thermal diffusivity and the shear viscosity in t…
Universal critical dynamics near the chiral phase transition and the QCD critical point
Yunxin Ye, Johannes V. Roth, Sören Schlichting +1
We use a novel real-time formulation of the functional renormalization group (FRG) for dynamical systems with reversible mode couplings to study Model G and H, which are the conjec…
Effects of dissipation on phase diagram and bosonic excitations in the quark-meson model
Johannes V. Roth, Yunxin Ye, Sören Schlichting +1
In this work we study the quark-meson model within a real-time formulation of the functional renormalization group (FRG) on the Schwinger-Keldysh contour. First, we discuss in deta…
Universal critical dynamics near the chiral phase transition and the QCD critical point
Johannes V. Roth, Yunxin Ye, Sören Schlichting +1
We use a novel real-time formulation of the functional renormalization group (FRG) for dynamical systems with reversible mode couplings to study Model H, the conjectured dynamic un…
Dynamic critical behavior of the chiral phase transition from the real-time functional renormalization group
Johannes V. Roth, Yunxin Ye, Sören Schlichting +1
In the chiral limit the complicated many-body dynamics around the second-order chiral phase transition of two-flavor QCD can be understood by appealing to universality. We present…
Critical dynamics in a real-time formulation of the functional renormalization group
Johannes V. Roth, Lorenz von Smekal
We present first calculations of critical spectral functions of the relaxational Models A, B, and C in the Halperin-Hohenberg classification using a real-time formulation of the fu…
Real-time methods for spectral functions
Johannes V. Roth, Dominik Schweitzer, Leon J. Sieke +1
In this paper we develop and compare different real-time methods to calculate spectral functions. These are classical-statistical simulations, the Gaussian state approximation (GSA…
