Quantum effects on unconventional pinch point singularities
Nils Niggemann, Yasir Iqbal, Johannes Reuther
Fracton phases are a particularly exotic type of quantum spin liquids where the elementary quasiparticles are intrinsically immobile. These phases may be described by unconventiona…
Classical and quantum phases of the pyrochlore magnet with Heisenberg and Dzyaloshinskii-Moriya interactions
Vincent Noculak, Daniel Lozano-Gómez, Jaan Oitmaa +4
We investigate the ground state and critical temperature phase diagrams of the classical and quantum pyrochlore lattice with nearest-neighbor Heisenberg and Dzyaloshinskii-…
Enhanced symmetry-breaking tendencies in the pyrochlore antiferromagnet
Imre Hagymási, Vincent Noculak, Johannes Reuther
We investigate the ground-state properties of the nearest-neighbor pyrochlore Heisenberg antiferromagnet using two complementary numerical methods, density-matrix renormaliza…
Pinch-points to half-moons and up in the stars: the kagome skymap
Dominik Kiese, Francesco Ferrari, Nikita Astrakhantsev +9
Pinch point singularities, associated with flat band magnetic excitations, are tell-tale signatures of Coulomb spin liquids. While their properties in the presence of quantum fluct…
