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 …

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

Antiferromagnetic materials have recently gained renewed interest due to their possible use
in spintronics technologies, where spin transport is the foundation of their functionalities. In …

The present review analyses and compares various types of dissipationless spin
transport:(1) Superfluid transport, when the spin-current state is a metastable state (a local …

Superfluid spin transport—dissipationless transport of spin—is theoretically studied in a
ferromagnetic insulator with easy-plane anisotropy. We consider an open geometry where …

We overview physical effects of exchange frustration and quantum spin fluctuations in (quasi-
) two dimensional (2D) quantum magnets (S= 1∕ 2) with square, rectangular and triangular …

The room-temperature dynamics of a magnon gas driven by short microwave pum**
pulses is studied. An overpopulation of the lowest energy level of the system following the …

We report a thorough theoretical study of the low temperature phase diagram of Cs 2 Cu Cl
4, a spatially anisotropic spin S= 1∕ 2 triangular lattice antiferromagnet, in a magnetic field …

The thermalization of parametrically pumped magnons caused by nonlinear multimagnon
scattering processes and leading to the magnon Bose-Einstein condensation is investigated …
