We present an extension of the concepts of the functional renormalization group approach to quantum many-body problems in non-equilibrium situations. The approach is completely general and allows calculations for both stationary and time-dependent situations. As a specific example we study the stati
We use a real-space renormalization group approach to calculate the thermodynamic properties of the isotropic antiferromagnetic nearest-neighbour Ising model on the triangular lattice. Our study confirms the important role played by frustration in determining the ground-state properties of the syst
