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…
Structural transition, spontaneous formation of strong singlet dimers and metamagnetism in magnetoelastic spin chains
C. J. Gazza, A. A. Aligia, A. O. Dobry +2
We study a one-dimensional antiferromagnetic-elastic model with magnetic ions having spin . By extensive DMRG computations and complementary analytical methods, we uncover a…
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…
Topological phases of strongly-interacting time-reversal invariant topological superconducting chains under a magnetic field
Leandro M. Chinellato, Claudio J. Gazza, Alejandro M. Lobos +1
Using the density-matrix renormalization group, we determine the different topological phases and low-energy excitations of a time-reversal invariant topological superconducting (T…
Double frustration and magneto-electro-elastic excitations in collinear multiferroic materials
D. C. Cabra, A. O. Dobry, C. J. Gazza +1
We discuss a model scenario for multiferroic systems of type II (collinear spins) where the electric dipolar order competes with a frustrated magnetic order in determining the elas…
