Partially disordered Heisenberg antiferromagnet with short-range stripe correlations
G. G. Blesio, F. T. Lisandrini, M. G. Gonzalez
Zero-point quantum fluctuations of a Néel order can produce effective interactions between quasi-orphan spins weakly coupled to the lattice. On the distort…
Influence of Rashba spin-orbit coupling on the 0- transition and Kondo temperature in 1D superconductors
I. Hamad, F. Lisandrini, C. Gazza +1
Using the framework of the density-matrix renormalization group (DMRG), we study a quantum dot coupled to a superconducting nanowire with strong Rashba spin-orbit coupling. Regardi…
Magnetic phase diagram of the infinite-U Hubbard model with nearest- and next nearest-neighbor hoppings
G. G. Blesio, M. G. Gonzalez, F. T. Lisandrini
We study the infinite-U Hubbard model on ladders of 2, 4 and 6 legs with nearest (t) and next-nearest (t') neighbor hoppings by means of the density-matrix renormalization group al…
Correlated partial disorder in a weakly frustrated quantum antiferromagnet
M. G. Gonzalez, F. T. Lisandrini, G. G. Blesio +3
Partial disorder --the microscopic coexistence of long-range magnetic order and disorder-- is a rare phenomenon, that has been experimental and theoretically reported in some Ising…
Width of the charge-transfer peak in the SU(N) impurity Anderson model and its relevance to non-equilibrium transport
J. Fernández, F. Lisandrini, P. Roura-Bas +2
We calculate the width and intensity of the charge-transfer peak (the one lying at the on-site energy ) in the impurity spectral density of states as a functi…
Topological Kondo insulators in one dimension: Continuous Haldane-type ground-state evolution from the strongly-interacting to the non-interacting limit
Franco T. Lisandrini, Alejandro M. Lobos, Ariel O. Dobry +1
We study, by means of the density-matrix renormalization group (DMRG) technique, the evolution of the ground state in a one-dimensional topological insulator, from the non-interact…
