Reading entanglement in terms of spin configurations in quantum magnets
Andrea Fubini, Tommaso Roscilde, Valerio Tognetti +2
We consider a quantum many-body system made of interacting spins on a lattice, and develop a formalism which allows to extract, out of conventional magnetic observabl…

Detection of XY behaviour in weakly anisotropic quantum antiferromagnets on the square lattice
Alessandro Cuccoli, Tommaso Roscilde, Ruggero Vaia +1
We consider the Heisenberg antiferromagnet on the square lattice with S=1/2 and very weak easy-plane exchange anisotropy; by means of the quantum Monte Carlo method, based on the c…
