Fracton Spin Liquid and Exotic Frustrated Phases in Ising-like Octochlore Magnets
Matthew Stern, Michael D. Burke, Michel J. P. Gingras +2
For nearly three decades, research on frustrated magnetism in three dimensions (3D) has centered on the pyrochlore lattice of corner-sharing tetrahedra and the classical spin liqui…

AKLT Hamiltonian from Hubbard tripods
Claire Benjamin, Dániel Varjas, Gábor Széchenyi +2
We investigate how the spin-1 Affleck-Kennedy-Lieb-Tasaki (AKLT) Hamiltonian can emerge from a microscopic fermionic model based on half-filled Hubbard tripods. We first show that…

Triplet nodal lines and Chern bands in XCuCl (X= K, Tl)
Charles B. Walker, Matthew Stern, Judit Romhányi
We investigate the symmetry-enforced line nodes of the triplet excitations of XCuCl (X= K, Tl), showing that they are protected by the nonsymmorphic symmetries and are unaffe…
