Coexistence of long-range and algebraic correlations for short-range valence-bond wave functions in three dimensions
A. Fabricio Albuquerque, Fabien Alet, Roderich Moessner
We investigate nearest-neighbor valence-bond wave functions on bipartite three-dimensional lattices. By performing large-scale Monte Carlo simulations, we find that long-range magn…
Phase Diagram of a Frustrated Quantum Antiferromagnet on the Honeycomb Lattice: Magnetic Order versus Valence-Bond Crystal formation
A. F. Albuquerque, D. Schwandt, B. Hetényi +3
We present a comprehensive computational study of the phase diagram of the frustrated S=1/2 Heisenberg antiferromagnet on the honeycomb lattice, with second-nearest (J2) and third-…
Critical Correlations for Short-Range Valence-Bond Wave Functions on the Square Lattice
A. Fabricio Albuquerque, Fabien Alet
We investigate the arguably simplest -invariant wave functions capable of accounting for spin-liquid behavior, expressed in terms of nearest-neighbor valence-bond states on…
Phase separation versus supersolid behavior in frustrated antiferromagnets
A. Fabricio Albuquerque, Nicolas Laflorencie, Jean-David Picon +1
We investigate the competition between spin-supersolidity and phase separation in a frustrated spin-half model of weakly coupled dimers. We start by considering systems of hard-cor…
Quantum Critical Scaling of Fidelity Susceptibility
A. Fabricio Albuquerque, Fabien Alet, Clément Sire +1
The behavior of the ground-state fidelity susceptibility in the vicinity of a quantum critical point is investigated. We derive scaling relations describing its singular behavior i…
Quantum Phase Diagram and Excitations for the One-Dimensional S=1 Heisenberg Antiferromagnet with Single-Ion Anisotropy
A. Fabricio Albuquerque, Chris J. Hamer, Jaan Oitmaa
We investigate the zero-temperature phase diagram of the one-dimensional S=1 Heisenberg antiferromagnet with single-ion anisotropy. By employing high-order series expansions and qu…
