Abstract The Bose–Einstein condensate (BEC) is a fascinating state of matter predicted to
occur for particles obeying Bose statistics. Although the BEC has been observed with …

There is a long time gap between the formulation of the basic theory of low-dimensional (low-
D) magnetism as advanced by Ising, Heisenberg and Bethe and its experimental …

Describing all aspects of the physics of transition metal compounds, this book provides a
comprehensive overview of this unique and diverse class of solids. Beginning with the basic …

Haldane topological materials contain unique antiferromagnetic chains with symmetry-
protected energy gaps. Such materials have potential applications in spintronics and future …

This article reviews experimental and theoretical work on Bose-Einstein condensation in
quantum magnets. These magnets are natural realizations of gases of interacting bosons …

Classical models of spin systems traditionally retain only the dipole moments, but a quantum
spin state will frequently have additional structure. Spins of magnitude S have N= 2 S+ 1 …

An interplay of geometrical frustration and strong quantum fluctuations in a spin-1/2
triangular-lattice antiferromagnet (TAF) can lead to exotic quantum states. Here, we report …

We present an introduction to the workings, units of measure, and general properties of
magnetic materials. This is intended as a “primer to interpretation of magnetic data” for those …

The low-temperature states of bosonic fluids exhibit fundamental quantum effects at the
macroscopic scale: the best-known examples are Bose–Einstein condensation and …

The Landau-Lifshitz equation describes the time evolution of magnetic dipoles and can be
derived by taking the classical limit of a quantum mechanical spin Hamiltonian. To take this …
