Dissipation effects in the Su-Schrieffer-Heeger model coupled to a metallic environment
Leandro M. Arancibia, Cristián G. Sánchez, Alejandro M. Lobos
We theoretically study the electronic and lattice properties of a trans-polyacetylene (tPA) molecule deposited on top of a metallic substrate at equilibrium. We describe the system…
Electrostatically-induced topological phase transitions in polyacetylene molecules
Tomás Suleiman, AnÃbal Iucci, Alejandro MartÃn Lobos
We study the electronic properties of a linear trans-polyacetylene (tPA) molecule capacitively coupled to an external gate voltage of width . We describe this system using…
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…
Spin-polarized transport and quantum phase transitions in one-dimensional superconductor-ferromagnetic insulator heterostructures
Javier Feijóo, AnÃbal Iucci, Alejandro M. Lobos
We theoretically propose a one-dimensional electronic nanodevice inspired in recently fabricated semiconductor-superconductor-ferromagnetic insulator (SE-SC-FMI) hybrid heterostruc…
Towards electrical domain-wall control in polyacetylene-based electronic nanodevices
Leandro M. Arancibia, Andrés I. Bertoni, Cristián G. Sánchez +1
We theoretically propose a polymer-based nano-device consisting of a single trans-polyacetylene (tPA) molecule capacitively coupled to external voltage gates. We model the integrat…
