Effective cutting of a quantum spin chain by bond impurities
T. J. G. Apollaro, F. Plastina, L. Banchi +4
Spin chains are promising media for short-haul quantum communication. Their usefulness is manifested in all those situations where stationary information carriers are involved. In…

Thermodynamics of the quantum easy-plane antiferromagnet on the triangular lattice
L. Capriotti, A. Cuccoli, V. Tognetti +2
The classical XXZ triangular-lattice antiferromagnet (TAF) shows both an Ising and a BKT transition, related to the chirality and the in-plane spin components, respectively. In thi…

The quantum Heisenberg antiferromagnet on the square lattice
A. Cuccoli, V. Tognetti, P. Verrucchi +1
The pure-quantum self-consistent harmonic approximation, a semiclassical method based on the path-integral formulation of quantum statistical mechanics, is applied to the study of…
