Highly-symmetric random one-dimensional spin models
V. L. Quito, Pedro L. S. Lopes, José A. Hoyos +1
The interplay of disorder and interactions is a challenging topic of condensed matter physics, where correlations are crucial and exotic phases develop. In one spatial dimension, a…
Random SU(2)-symmetric spin- chains
V. L. Quito, José A. Hoyos, E. Miranda
We study the low-energy physics of a broad class of time-reversal invariant and SU(2)-symmetric one-dimensional spin-S systems in the presence of quenched disorder via a strong-dis…
Emergent SU(3) symmetry in random spin-1 chains
V. L. Quito, José A. Hoyos, E. Miranda
We show that generic SU(2)-invariant random spin-1 chains have phases with an emergent SU(3) symmetry. We map out the full zero-temperature phase diagram and identify two different…
Valence-bond theory of highly disordered quantum antiferromagnets
S. Zhou, J. A. Hoyos, V. Dobrosavljevic +1
We present a large-N variational approach to describe the magnetism of insulating doped semiconductors based on a disorder-generalization of the resonating-valence-bond theory for…
