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

A theoretical overview of the phenomenon of spontaneous magnon decays in quantum
antiferromagnets is presented. The intrinsic zero-temperature dam** of magnons in …

We introduce a classical limit of the dynamics of quantum spin systems based on coherent
states of SU (N), where N is the dimension of the local Hilbert space. This approach, which …

We apply a recently developed thermal form factor expansion method to evaluate the real-
time longitudinal spin-spin correlation functions of the spin-1 2 XXZ chain in the …

We present the magnetic and structural properties of [Cu (pyrazine) 0.5 (glycine)] ClO 4
under applied pressure. As previously reported, at ambient pressure this material consists of …

The quantum dimer magnet (QDM) is the canonical example of quantum magnetism. The
QDM state consists of entangled nearest-neighbor spin dimers and often exhibits a field …

Transport properties provide important access to a solid's quasiparticles, such as
quasiparticle density, mobility, and scattering. The transport of heat can be particularly …

Quantum magnets admit more than one classical limit and N-level systems with strong
single-ion anisotropy are expected to be described by a classical approximation based on …

Bose–Einstein condensation (BEC) is a quantum phenomenon in which a macroscopic
number of bosons occupy the lowest energy state and acquire coherence at low …

We use a generalized spin-wave approach and large-scale quantum Monte Carlo (QMC)
simulations to study the quantum phase diagram and quasiparticle excitations of the S= 1 …
