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…
Emergent SU(N) symmetry in disordered SO(N) spin chains
V. L. Quito, Pedro L. S. Lopes, José A. Hoyos +1
Strongly disordered spin chains invariant under the SO(N) group are shown to display random-singlet phases with emergent SU(N) symmetry without fine tuning. The phases with emergen…
Topological strings linking with quasi-particle exchange in superconducting Dirac semimetals
Pedro L. S. Lopes, Jeffrey C. Y. Teo, Shinsei Ryu
We demonstrate a topological classification of vortices in three dimensional time-reversal invariant topological superconductors based on superconducting Dirac semimetals with an s…
