Frustration and Dzyaloshinsky-Moriya anisotropy in the kagome francisites CuBi(SeOOX
Ioannis Rousochatzakis, Johannes Richter, Ronald Zinke +1
We investigate the antiferromagnetic canting instability of the spin-1/2 kagome ferromagnet, as realized in the layered cuprates CuBi(SeOOX (X=Br, Cl, and I). While…
Quantum Spin Ice and dimer models with Rydberg atoms
Alexander W. Glaetzle, Marcello Dalmonte, Rejish Nath +3
Quantum spin ice represents a paradigmatic example on how the physics of frustrated magnets is related to gauge theories. In the present work we address the problem of approximatel…
The quantum origins of skyrmions and half-skyrmions in Cu2OSeO3
O. Janson, I. Rousochatzakis, A. A. Tsirlin +5
The Skyrme-particle, the , was introduced over half a century ago and used to construct field theories for dense nuclear matter. But with skyrmions being mathematical obj…
Strongly frustrated triangular spin lattice emerging from triplet dimer formation in honeycomb Li2IrO3
Satoshi Nishimoto, Vamshi M. Katukuri, Viktor Yushankhai +5
In quantum magnetism spin dimers are typically associated with spin-singlet states. To date, has not been observed in any 3D or quasi-2D material. With thi…
Entangled tetrahedron ground state and excitations of the magneto-electric skyrmion material CuOSeO
Judit Romhányi, Jeroen van den Brink, Ioannis Rousochatzakis
The strongly correlated cuprate CuOSeO has recently been identified as the first insulating system exhibiting a skyrmion lattice phase. Using a microscopic multi-boson theo…
Mechanism of basal-plane antiferromagnetism in the spin-orbit driven iridate Ba2IrO4
Vamshi M. Katukuri, Viktor Yushankhai, Liudmila Siurakshina +3
By ab initio many-body quantum chemistry calculations, we determine the strength of the symmetric anisotropy in the 5 j 1/2 layered material BaIrO. While the…
