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…
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…
Slow light transmission in one-dimensional periodic structures
O. del Barco, M. Ortuño
We have analyzed the transmission properties of pulses through one-dimensional periodic structures in order to systematically explore the best conditions to achieve the maximum del…
Green functions of interacting systems in the strongly localized regime
A. N. Somoza, M. Ortuño, V. Gasparian +1
We have developed an approach to calculate the single-particle Green function of a one-dimensional many-body system in the strongly localized limit at zero temperature. Our approac…
