Multiorbital effects in the functional renormalization group: A weak-coupling study of the Emery model
Stefan A. Maier, Jutta Ortloff, Carsten Honerkamp
We perform an instability analysis of the Emery three-band model at hole doping and weak coupling within a channel-decomposed functional renormalization group flow proposed in Phys…
Magnetic properties of a family of quinternary oxalates
E. Lhotel, V. Simonet, J. Ortloff +8
We report on the magnetic properties of four isomorphous compounds of a family of quinternary oxalates down to 60 mK. In all these materials, the magnetic FeII ions with a strong m…
An alternative functional renormalization group approach to the single impurity Anderson model
Michael Kinza, Jutta Ortloff, Johannes Bauer +1
We present an alternative functional renormalization group (fRG) approach to the single-impurity Anderson model at finite temperatures. Starting with the exact self-energy and inte…
Domain Wall Spin Dynamics in Kagome Antiferromagnets
E. Lhotel, V. Simonet, J. Ortloff +8
We report magnetization and neutron scattering measurements down to 60 mK on a new family of Fe based kagome antiferromagnets, in which a strong local spin anisotropy combined with…
Effective low-energy Hamiltonians for interacting nanostructures
Michael Kinza, Jutta Ortloff, Carsten Honerkamp
We present a functional renormalization group (fRG) treatment of trigonal graphene nanodiscs and composites thereof, modeled by finite-size Hubbard-like Hamiltonians with honeycomb…
Non-perturbative conserving approximations and Luttinger's sum rule
Jutta Ortloff, Matthias Balzer, Michael Potthoff
Weak-coupling conserving approximations can be constructed by truncations of the Luttinger-Ward functional and are well known as thermodynamically consistent approaches which respe…
