Bose-Einstein condensation vs. localization of bosonic quasiparticles in disordered weakly-coupled dimer antiferromagnets
Tommaso Roscilde, Stephan Haas
We investigate the field-induced insulator-to-superfluid transition of bosonic quasiparticles in weakly-coupled dimer antiferromagnets. In presence of realistic disorder du…
Quantum disorder and Griffiths singularities in bond-diluted two-dimensional Heisenberg antiferromagnets
Rong Yu, Tommaso Roscilde, Stephan Haas
We investigate quantum phase transitions in the spin-1/2 Heisenberg antiferromagnet on square lattices with inhomogeneous bond dilution. It is shown that quantum fluctuations can b…
Quantum localization in bilayer Heisenberg antiferromagnets with site dilution
Tommaso Roscilde, Stephan Haas
The field-induced antiferromagnetic ordering in systems of weakly coupled S=1/2 dimers at zero temperature can be described as a Bose-Einstein condensation of triplet quasiparticle…
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…
Quantum Heisenberg antiferromagnets: a survey of the activity in Firenze
Umberto Balucani, Luca Capriotti, Alessandro Cuccoli +5
Over the years the research group in Firenze has produced a number of theoretical results concerning the statistical mechanics of quantum antiferromagnetic models, which range from…
