Inhomogeneous quantum antiferromagnetism on periodic lattices
A. Jagannathan, R. Moessner, S. Wessel
We study quantum antiferromagnets on two-dimensional bipartite lattices. We focus on local variations in the properties of the ordered phase which arise due to the presence of ineq…
Linear independence of localized magnon states
Heinz-Jürgen Schmidt, Johannes Richter, Roderich Moessner
At the magnetic saturation field, certain frustrated lattices have a class of states known as "localized multi-magnon states" as exact ground states. The number of these states sca…
Electron interactions in graphene in a strong magnetic field
M. O. Goerbig, R. Moessner, B. Doucot
Graphene in the quantum Hall regime exhibits a multi-component structure due to the electronic spin and chirality degrees of freedom. While the applied field breaks the spin symmet…
Artificial square ice and related dipolar nanoarrays
Gunnar Moller, R. Moessner
We study a frustrated dipolar array recently manufactured lithographically by Wang {\em et al.} [Nature {\bf 439}, 303 (2006)] in order to realize the square ice model in an artifi…
Unconventional continuous phase transition in a three dimensional dimer model
Fabien Alet, Gregoire Misguich, Vincent Pasquier +2
Phase transitions occupy a central role in physics, due both to their experimental ubiquity and their fundamental conceptual importance. The explanation of universality at phase tr…
Two geometrically frustrated magnets studied by neutron diffraction
I. Mirebeau, A. Apetrei, I. N. Goncharenko +1
In the pyrochlore compounds, TbTiO and TbSnO, only the Tb ions are magnetic. They exhibit quite abnormal -- and, in view of their chemical similarity…
