Functional renormalization group with vacuum expectation values and spontaneous symmetry breaking
Florian Schuetz, Peter Kopietz
We generalize our recently developed super-field functional renormalization group (RG) method involving both Fermi and Bose fields [F. Schuetz, L. Bartosch, and P. Kopietz, Phys. R…
Effective spin-wave action for ordered Heisenberg antiferromagnets in a magnetic field
Nils Hasselmann, Florian Schuetz, Ivan Spremo +1
We derive the effective long-wavelength Euclidean action for the antiferromagnetic spin-waves of ordered quantum antiferromagnets subject to a uniform magnetic field. We point out…
Magnetic properties of a metal-organic antiferromagnet on a distorted honeycomb lattice
Ivan Spremo, Florian Schuetz, Peter Kopietz +6
For temperatures T well above the ordering temperature T*=3.0+-0.2K the magnetic properties of the metal-organic material Mn[C10H6(OH)(COO)]2x2H20 built from Mn^2+ ions and 3-hydro…
