TL;DR: Real-space imaging of a two-dimensional skyrmion lattice in a thin film of Fe0.5Co 0.5Si using Lorentz transmission electron microscopy reveals a controlled nanometre-scale spin topology, which may be useful in observing unconventional magneto-transport effects.

Skyrmion lattice in a two-dimensional chiral magnet
TL;DR: In this paper, the authors developed a theory of the magnetic field-induced formation of Skyrmion crystal state in chiral magnets in two spatial dimensions, motivated by the recent discovery of the Skyrmic phase of magnetization in thin film of Fe 0.5 and MnSi.

Nematic and chiral order for planar spins on a triangular lattice.
TL;DR: A variant of the antiferromagnetic XY model which includes a biquadratic as well as the quadratic interaction on the triangular lattice is proposed, which qualifies as the first instance of a classical spin model that exhibits a vector chiral spin liquid phase.

Manifold mixing in the temporal evolution of a spin-1 spinor Bose-Einstein condensate.
TL;DR: Dynamical constraints unique to each submanifold are derived for the first time, demonstrating that efforts to write down hydrodynamic theory in one specific manifold are generally invalid.

Arbitrary Chern number generation in the three-band model from momentum space
TL;DR: In this article, a simple general rule for generating a three-band model with arbitrary Chern numbers is given, based on the idea of monopole charge-changing unitary operations and can be realized by two types of simple unitary operation on the original Hamiltonian.
