Electric field driven flat bands: Enhanced magnetoelectric and electrocaloric effects in frustrated quantum magnets
Johannes Richter, Vadim Ohanyan, Jörg Schulenburg +1
The - quantum spin sawtooth chain is a paradigmatic one-dimensional frustrated quantum spin system exhibiting unconventional ground-state and finite-temperature propertie…
Anomalous thermodynamics of a quantum spin system with large residual entropy
J. Richter, J. Schulenburg, D. V. Dmitriev +2
In contrast to strongly frustrated classical systems, their quantum counterparts typically have a non-degenerate ground state. A counterexample is the celebrated Heisenberg sawtoot…
Magnon crystallization in the kagome lattice antiferromagnet
J. Schnack, J. Schulenburg, A. Honecker +1
We present numerical evidence for the crystallization of magnons below the saturation field at non-zero temperatures for the highly frustrated spin-half kagome Heisenberg antiferro…
The Interplay Between Lattice Topology, Frustration, and Spin Quantum Number in Quantum Antiferromagnets on Archimedean Lattices
D. J. J. Farnell, O. Götze, J. Schulenburg +3
The interplay between lattice topology, frustration, and spin quantum number, , is explored for the Heisenberg antiferromagnet (HAFM) on the eleven two-dimensional Archimedean l…
Magnetism of the N=42 kagome lattice antiferromagnet
J. Schnack, J. Schulenburg, J. Richter
For the paradigmatic frustrated spin-half Heisenberg antiferromagnet on the kagome lattice we performed large-scale numerical investigation of thermodynamic functions by means of t…
Frustrated honeycomb-lattice bilayer quantum antiferromagnet in a magnetic field
Taras Krokhmalskii, Vasyl Baliha, Oleg Derzhko +2
Frustrated bilayer quantum magnets have attracted attention as flat-band spin systems with unconventional thermodynamic properties. We study the low-temperature properties of a fru…
