Spin- model with competing interactions on diamond-decorated lattices
D. V. Dmitriev, V. Ya. Krivnov, O. A. Vasilyev
We investigate the ground state properties, magnetization, and low-temperature thermodynamics of the ferromagnetic-antiferromagnetic spin- model on diamond-decorated lattices wi…

Frustrated spin models on two- and three-dimensional decorated lattices with high residual entropy
D. V. Dmitriev, V. Ya. Krivnov, O. A. Vasilyev
We study the ground-state properties of a family of frustrated spin-1/2 Heisenberg models on two- and three-dimensional decorated lattices composed of connected star-shaped units.…

Action at the distance
D. B. Abraham, A. Maciolek, O. Vasilyev
We present a system exhibiting giant proximity effects which parallel observations in superfluid helium (Perron et al, Nature Physics V. 6, 499 (2010)) and give a theoretical expla…
