RIXS observation of bond-directional nearest-neighbor excitations in the Kitaev material NaIrO
M. Magnaterra, K. Hopfer, Ch. J. Sahle +13
Spin-orbit coupling locks spin direction and spatial orientation and generates, in semi-classical magnets, a local spin easy-axis and associated ordering. Quantum spin-1/2's defy t…
Supersymmetry on the lattice: Geometry, Topology, and Flat Bands
Krishanu Roychowdhury, Jan Attig, Simon Trebst +1
In quantum mechanics, supersymmetry (SUSY) posits an equivalence between two elementary degrees of freedom, bosons, and fermions defined by local rules. Here we apply it to find co…
Quasimolecular electronic structure of the spin-liquid candidate BaInIrO
A. Revelli, M. Moretti Sala, G. Monaco +16
The mixed-valent iridate Ba3InIr2O9 has been discussed as a promising candidate for quantum spin-liquid behavior. The compound exhibits Ir ions in face-sharing IrO6 octahe…
Spin-orbit entangled j=1/2 moments in BaCeIrO -- a frustrated fcc quantum magnet
A. Revelli, C. C. Loo, D. Kiese +16
We establish the double perovskite BaCeIrO as a nearly ideal model system for j=1/2 moments, with resonant inelastic x-ray scattering indicating a deviation of less than 1%…
Topological Mechanics from Supersymmetry
Jan Attig, Krishanu Roychowdhury, Michael J. Lawler +1
In topological mechanics, the identification of a mechanical system's rigidity matrix with an electronic tight-binding model allows to infer topological properties of the mechanica…
Two-stage multipolar ordering in Pr(TM)Al Kondo materials
Frederic Freyer, Jan Attig, SungBin Lee +3
Among heavy fermion materials, there is a set of rare-earth intermetallics with non-Kramers Pr moments which exhibit a rich phase diagram with intertwined quadrupolar…
Classical Spin Spirals in Frustrated Magnets from Free-Fermion Band Topology
Jan Attig, Simon Trebst
The formation of coplanar spin spirals is a common motif in the magnetic ordering of many frustrated magnets. For classical antiferromagnets, geometric frustration can lead to a ma…
