The idea that a quantum magnet could act like a liquid crystal, breaking spin-rotation symmetry without breaking time-reversal symmetry, holds an abiding fascination. However …
We study CP 2 skyrmion crystals in the ferromagnetic SU (3) Heisenberg model with a generalization of the Dzyaloshinskii-Moriya interaction and the Zeeman term. The model …
Theoretical studies of magnets have traditionally concentrated on either classical spins, or the extreme quantum limit of spin-1/2. However, magnets built of spin-1 moments are also …
Abstract The interfacial Dzyaloshinskii–Moriya Interaction can modify the topology of droplets excited by a localized spin-polarized current. Here, we show that, in addition to the …
We study two dimensional soliton solutions in the CP 2 nonlinear sigma model with a Dzyaloshinskii-Moriya type interaction. First, we derive such a model as a continuous limit of …

We study the dynamics and relaxation of elementary excitations (magnons) in the spin nematic (quadrupole ordered) phase of S= 1 magnets. We develop a general …
We develop a theory of spin excitations in a field-induced spin-nematic state, and use it to show how a spin-nematic order can be indentified using inelastic neutron scattering. We …

Here we consider micron-sized samples with any axisymmetric body shape and made with a canted antiferromagnet, like hematite or iron borate. We find that its ground state can be a …
Cold atoms bring new opportunities to study quantum magnetism, and in particular, to simulate quantum magnets with symmetry greater than SU (2). Here we explore the …
