Encrypting Majorana Fermions-qubits as Bound States in the Continuum
L. H. Guessi, F. A. Dessotti, Y. Marques +5
We theoretically investigate a topological Kitaev chain connected to a double quantum-dot (QD) setup hybridized with metallic leads. In this system we observe the emergence of two…
Unveiling Majorana Quasiparticles by a Quantum Phase Transition: Proposal of a Current Switch
F. A. Dessotti, L. S. Ricco, Y. Marques +6
We propose a theoretical approach based on an interferometer composed by two quantum dots asymmetrically coupled to isolated Majorana quasiparticles (MQPs), lying on the edges of t…
Quantum phase transition triggering magnetic BICs in graphene
L. H. Guessi, Y. Marques, R. S. Machado +6
Graphene hosting a pair of collinear adatoms in the phantom atom configuration has pseudogap with cubic scaling on energy, which leads to the appearance…
Catching the Bound States in the Continuum of a Phantom Atom in Graphene
L. H. Guessi, R. S. Machado, Y. Marques +6
We explore theoretically the formation of bound states in the continuum (BICs) in graphene hosting two collinear adatoms situated at different sides of the sheet and at the center…
Fano fingerprints of Majoranas in Kitaev dimers of superconducting adatoms
F. A. Dessotti, L. S. Ricco, Y. Marques +5
We investigate theoretically a Fano interferometer composed by STM and AFM tips close to a Kitaev dimer of superconducting adatoms, in which the adatom placed under the AFM tip, en…
Effect of Inter-Adatoms Correlations on the Local Density of States of Graphene
A. C. Seridonio, K. Kristinsson, M. de Souza +4
We discuss theoretically the local density of states (LDOS) of a graphene sheet hosting two distant adatoms located at the center of the hexagonal cells. By putting laterally a Sca…
Dimensionality effects in the LDOS of ferromagnetic hosts probed via STM: spin-polarized quantum beats and spin filtering
A. C. Seridonio, S. C. Leandro, L. H. Guessi +5
We theoretically investigate the local density of states (LDOS) probed by a STM tip of ferromagnetic metals hosting a single adatom and a subsurface impurity. We model the system v…
