Design Principles for Quasi-Isotropic Exchange in Rare-Earth Quantum Magnets
Kotaro Shimizu, Esteban Agustin Ghioldi, Filip Ronning +1
Rare-earth quantum materials provide a promising platform for emergent phenomena ranging from quantum spin liquids with long-range entanglement to topological magnetic textures. Ho…

Spin dynamics of the spin-1 triangular lattice Heisenberg antiferromagnet KNi(SeO)
Chaebin Kim, Sathvik Nallapati, E. A. Ghioldi +6
Strong quantum fluctuations and unconventional spin dynamics are well established in the spin-1/2 triangular lattice Heisenberg antiferromagnet. However, their survival in the spin…

Nonlinear light cone spreading of correlations in a triangular quantum magnet: a hard quantum simulation target
A. Scheie, J. Willsher, E. A. Ghioldi +6
Dynamical correlations of quantum many-body systems are typically analyzed in the momentum space and frequency basis. However, quantum simulators operate more naturally in real spa…
