Renormalization group flows into phases with broken symmetry

Manfred Salmhofer, Carsten Honerkamp, Walter Metzner +1

We describe a way to continue the fermionic renormalization group flow into phases with broken global symmetry. The method does not require a Hubbard-Stratonovich decoupling of the…

Magnetism in Carbon Structures

Pablo Esquinazi, Roland Höhne

We discuss different magnetic phenomena observed in carbon-based structures, in particular the diamagnetism, paramagnetism and ferromagnetism observed in graphite, disordered carbo…

Green's-function theory of the Heisenberg ferromagnet in a magnetic field

I. Junger, D. Ihle, J. Richter +1

We present a second-order Green's-function theory of the one- and two-dimensional S=1/2 ferromagnet in a magnetic field based on a decoupling of three-spin operator products, where…

Spin-lattice coupling effects in the Holstein double-exchange model

Alexander Weisse, Holger Fehske, Dieter Ihle

Based on the Holstein double-exchange model and a highly efficient single cluster Monte Carlo approach we study the interplay of double-exchange and polaron effects in doped coloss…

Absence of long-range order in a spin-half Heisenberg antiferromagnet on the stacked kagome lattice

D. Schmalfuss, J. Richter, D. Ihle

We study the ground state of a spin-half Heisenberg antiferromagnet on the stacked kagome lattice by using a spin-rotation-invariant Green's-function method. Since the pure two-dim…
