Probing Boundary Spins in the Su-Schrieffer-Heeger-Hubbard model
Armando A. Aligia, Alejandro M. Lobos, Lucila Peralta Gavensky +1
Studying boundary excitations provides a powerful approach to probe correlations in topological phases. We propose that localized spins near the ends of a Su-Schrieffer-Heeger-Hubb…

Nontrivial entanglement passively mediated by a quenched magnetic impurity
Adelina A. Orlandini, Germán G. Blesio, Claudio J. Gazza +1
We investigate the entanglement properties of a Kondo system undergoing a transition to a state with a quenched magnetic impurity, using the density matrix renormalization group (D…

Thermal decay of two-spinon bound states in quasi-2D triangular antiferromagnets
I. L. Pomponio, E. A. Ghioldi, C. J. Gazza +2
We analyze the temperature evolution of the anomalous magnetic spectrum of the spin-1/2 triangular quantum Heisenberg antiferromagnet, which is proximate to a quantum phase transit…
