Emergent Symmetry at the Néel to Valence-Bond-Solid Transition
Adam Nahum, P. Serna, J. T. Chalker +2
We show numerically that the `deconfined' quantum critical point between the Néel antiferromagnet and the columnar valence-bond-solid, for a square lattice of spin-1/2s, has an eme…

Topological Constraints in Directed Polymer Melts
Pablo Serna, Guy Bunin, Adam Nahum
Polymers in a melt may be subject to topological constraints, as in the example of unlinked polymer rings. How to do statistical mechanics in the presence of such constraints remai…

Deconfined Quantum Criticality, Scaling Violations, and Classical Loop Models
Adam Nahum, J. T. Chalker, P. Serna +2
Numerical studies of the Néel to valence-bond solid phase transition in 2D quantum antiferromagnets give strong evidence for the remarkable scenario of deconfined criticality, but…
