Symmetry-broken perturbation theory to large orders in antiferromagnetic phases
R. Garioud, F. Šimkovic, R. Rossi +4
We introduce a spin-symmetry-broken extension of the connected determinant algorithm [Phys. Rev. Lett. 119, 045701 (2017)]. The resulting systematic perturbative expansions around…
Far-off-equilibrium expansion trajectories in the QCD phase diagram
Chandrodoy Chattopadhyay, Ulrich Heinz, Thomas Schaefer
We consider the hydrodynamic evolution of a quark-gluon gas with non-zero quark masses and net baryon number in its phase diagram. For far-off-equilibrium initial conditions the ex…
Dynamics of non-Gaussian fluctuations in model A
Thomas Schaefer, Vladimir Skokov
Motivated by the experimental search for the QCD critical point we perform simulations of a stochastic field theory with purely relaxational dynamics (model A). We verify the expec…
Strongly correlated superconductivity with long-range spatial fluctuations
Motoharu Kitatani, Ryotaro Arita, Thomas Schäfer +1
We review recent studies for superconductivity using diagrammatic extensions of dynamical mean field theory. These approaches take into account simultaneously both, the local corre…
