Dzyaloshinskii-Moriya-driven instabilities in square-kagome quantum antiferromagnets
Leonid S. Taran, Arnaud Ralko, Fedor V. Temnikov +3
Decorated square-kagome quantum antiferromagnets provide a natural setting in which strong frustration, lattice decoration, and spin-orbit-induced anisotropy compete on comparable…
Tetrahedral Core in a Sea of Competing Magnetic Phases in Graphene
Maxime Lucas, Arnaud Ralko, Andreas Honecker +1
We demonstrate the emergence of a robust tetrahedral magnetic ground state in monolayer graphene doped to the van Hove singularity (vHS). This noncoplanar, gapped spin configuratio…
Exact ground state on the 3D analogue of the Shastry-Sutherland model
Kelvin Salou-Smith, Arnaud Ralko, Ludovic D. C. Jaubert
Exact results in frustrated quantum many-body systems are rare, especially in dimensions higher than one. The Shastry-Sutherland (SS) model stands out as a rare example of a two-di…
The emergence of Resonating Valence Bond physics in spin-orbital models
F. Mila, F. Vernay, A. Ralko +3
We discuss how orbital degeneracy, which is usually removed by a cooperative Jahn-Teller distortion, could under appropriate circumstances lead rather to a Resonating Valence Bond…
