Quantum-critical scaling properties of the two-dimensional random-singlet state
Lu Liu, Wenan Guo, Anders W. Sandvik
We use QMC simulations to study effects of disorder on the Heisenberg model with exchange constant on the square lattice supplemented by multispin interactions . It…
Extreme Suppression of Antiferromagnetic Order and Critical Scaling in a Two-Dimensional Random Quantum Magnet
Wenshan Hong, Lu Liu, Chang Liu +16
SrCuTeO is a square-lattice Néel antiferromagnet with superexchange between first-neighbor Cu spins mediated by plaquette centered Te ions. Substituting Te by W, th…
Typicality at quantum-critical points
Lu Liu, Anders W. Sandvik, WenAn Guo
We discuss the concept of typicality of quantum states at quantum-critical points, using projector Monte Carlo simulations of an bilayer Heisenberg antiferromagnet as an il…
Random-Singlet Phase in Disordered Two-Dimensional Quantum Magnets
Lu Liu, Hui Shao, Yu-Cheng Lin +2
We study effects of disorder (randomness) in a 2D square-lattice quantum spin system, the - model with a 6-spin interaction supplementing the Heisenberg exchange…
