Noncoplanar orders and quantum disordered states in maple-leaf (anti)ferromagnets
Martin Gembé, Lasse Gresista, Heinz-Jürgen Schmidt +3
A promising route towards the realization of chiral spin liquids is the quantum melting of classically noncoplanar spin states via quantum fluctuations. In the classical realm, suc…
Exotic magnetization curves in classical square-kagomé spin lattices
Heinz-Jürgen Schmidt, Johannes Richter
Classical spin systems with non-coplanar ground states typically exhibit nonlinear magnetization curves characterized by kinks and jumps. Our article briefly summarizes the most im…
Non-Coplanar Magnetic Orders in Classical Square-Kagome Antiferromagnets
Martin Gembé, Heinz-Jürgen Schmidt, Ciarán Hickey +3
Motivated by the recent synthesis of a number of Mott insulating square-kagome materials, we explore the rich phenomenology of frustrated magnetism induced by this lattice geometry…
High-temperature expansion for frustrated magnets: Application to the J1-J2 model on the BCC lattice
Johannes Richter, Patrick Müller, Andre Lohmann +1
We present the high-temperature expansion up to 11th order for the specific heat and the uniform susceptibility and up to 9th order for the structure factor o…
Magnetic susceptibility of frustrated spin-s J1-J2 quantum Heisenberg magnets: High-temperature expansion and exact diagonalization data
J. Richter, A. Lohmann, H. -J. Schmidt +1
Motivated by recent experiments on low-dimensional frustrated quantum magnets with competing nearest-neighbor exchange coupling J1 and next nearest-neighbor exchange coupling J2 we…
Tenth-order high-temperature expansion for the susceptibility and the specific heat of spin-s Heisenberg models with arbitrary exchange patterns: Application to pyrochlore and kagome magnets
Andre Lohmann, Heinz-Jürgen Schmidt, Johannes Richter
We present the high-temperature expansion (HTE) up to 10th order of the specific heat C and the uniform susceptibility χfor Heisenberg models with arbitrary exchange patterns and a…
Macroscopic magnetization jumps due to independent magnons in frustrated quantum spin lattices
J. Schulenburg, A. Honecker, J. Schnack +2
For a class of frustrated spin lattices including the kagome lattice we construct exact eigenstates consisting of several independent, localized one-magnon states and argue that th…
