The fate of pairing and spin-charge separation in the presence of long-range antiferromagnetism
Luhang Yang, Ignacio Hamad, Luis O. Manuel +1
We present a numerical study of competing orders in the 1D - model with long-range RKKY-like staggered spin interactions. By circumventing the constraints imposed by Mermin-W…
Magnon-assisted dynamics of a hole doped in a cuprate superconductor
I. J. Hamad, L. O. Manuel, A. A. Aligia
We calculate the quasiparticle dispersion and spectral weight of the quasiparticle that results when a hole is added to an antiferromagnetically ordered CuO plane of a cuprate…
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…
Generalized one-band model based on Zhang-Rice singlets for Tetragonal CuO
I. J. Hamad, L. O. Manuel, A. A. Aligia
Tetragonal CuO (T-CuO) has attracted attention because of its structure similar to that of the cuprates. It has been recently proposed as a compound whose study can give an end to…
Helical currents in metallic Rashba strips
Ignacio J. Hamad, Claudio J. Gazza, Jose A. Riera
We study the texture of helical currents in metallic planar strips in the presence of Rashba spin-orbit coupling (RSOC) on the lattice at zero temperature. In the noninteracting ca…
Transport Regimes in a Double Quantum Dot Device
L. Costa Ribeiro, I. J. Hamad, G. Chiappe +1
We analyze the transport properties of a double quantum dot device with both dots coupled to perfect conducting leads and to a finite chain of N non-interacting sites connecting bo…
