Resilience of topological superconductivity under particle current
Alfonso Maiellaro, Francesco Romeo, Fabrizio Illuminati +1
We investigate the robustness of topological superconductors under the perturbing influence of a finite charge current. To this aim, we introduce a modified Kitaev Hamiltonian para…
Hallmarks of non-trivial topology in Josephson junctions based on oxide nanochannels
Alfonso Maiellaro, Jacopo Settino, Claudio Guarcello +2
We investigate the topological properties of a Josephson junction obtained by constraining a two-dimensional electron gas at oxide interface to form a quasi-1D conductor. We reveal…
Squashed entanglement in one-dimensional quantum matter
Alfonso Maiellaro, Francesco Romeo, Roberta Citro +1
Squashed entanglement and its universal upper bound, the quantum conditional mutual information, are faithful measures of bipartite quantum correlations defined in terms of multipa…
Topological phases of an interacting Majorana Benalcazar-Bernevig-Hughes model
Alfonso Maiellaro, Fabrizio Illuminati, Roberta Citro
We study the effects of Coulomb repulsive interactions on a Majorana Benalcazar-Bernevig-Hughes (MBBH) model. The MBBH model belongs to the class of second--order topological super…
Topological squashed entanglement: nonlocal order parameter for one-dimensional topological superconductors
Alfonso Maiellaro, Antonio Marino, Fabrizio Illuminati
Identifying entanglement-based order parameters characterizing topological systems, in particular topological superconductors and topological insulators, has remained a major chall…
