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 …

The 2-dimensional layered oxide material SrCu2 (BO3) 2, long studied as a realization of
the Shastry-Sutherland spin topology, exhibits a range of intriguing physics as a function of …

We study a system of heteronuclear molecules on a triangular lattice and analyze the
potential of this system for the experimental realization of a supersolid phase. The ground …

This article discusses at a qualitative level a number of issues at the forefront of current
understanding and developments in frustrated quantum magnetism. The focal point of the …

We use numerical methods to demonstrate that the phase diagram of S= 1 Heisenberg
models with uniaxial anisotropy contains an extended supersolid phase. We show that this …

We study phase transitions and hysteresis in a system of dipolar bosons loaded into
triangular optical lattices at zero temperature. We find that the quantum melting transition …

We show that correlated hopping of triplets, which is often the dominant source of kinetic
energy in dimer-based frustrated quantum magnets, produces a remarkably strong tendency …

The application of an external magnetic field of sufficient strength to a spin system
composed of a localized singlet can overcome the energy gap and trigger bosonic …

We investigate the thermodynamic properties of a field-induced supersolid phase in a 2D
quantum antiferromagnet model. Using quantum Monte Carlo simulations, a very rich phase …
