Spiral spin liquids are unique classical spin liquids that occur in many frustrated spin
systems, but do not comprise a new phase of matter. Owing to extensive classical ground …

The Kitaev model, a honeycomb network of spins with bond-dependent anisotropic
interactions, is a rare example of a system with a quantum spin liquid ground state. Although …

Spin liquids are a paradigmatic example of a nontrivial state of matter. The search for new
spin liquids is a key interdisciplinary challenge. Geometrical frustration─ where the …

Simulating quantum spin systems at finite temperatures is an open challenge in many-body
physics. This work studies the temperature-dependent spin dynamics of a pivotal compound …

We study the dynamical structure factor of the spin-1 pyrochlore material NaCaNi 2 F 7,
which is well described by a weakly perturbed nearest-neighbour Heisenberg Hamiltonian …

The discovery of magnetism in ultrathin crystals opens up opportunities to explore new
physics and to develop next-generation spintronic devices. Nevertheless, two-dimensional …

Magnetic order is usually associated with well-defined magnon excitations. Exotic magnetic
fluctuations with fractional, topological or multipolar character have been proposed for …

In this paper we identify a previously unexplored type of topological defect in spiral spin
liquids—the momentum vortex—and reveal its dominant role in sha** the low-energy …

Spiral spin liquids are an exotic class of correlated paramagnets with an enigmatic magnetic
ground state composed of a degenerate manifold of fluctuating spin spirals. Experimental …

We address the long-standing problem of the microscopic origin of the richly diverse
phenomena in the chromium breathing pyrochlore material family. Combining electronic …
