Interaction induced hybridization of Majorana zero-modes in a coupled quantum-dot hybrid-nanowire system
L. S. Ricco, Y. Marques, J. E. Sanches +2
We study the low-energy transport properties of a hybrid device composed by a native quantum dot coupled to both ends of a topological superconducting nanowire section hosting Majo…
Majorana molecules and their spectral fingerprints
J. E. Sanches, L. S. Ricco, W. N. Mizobata +4
We introduce the concept of a Majorana molecule, a topological bound state appearing in the geometry of a double quantum dot (QD) structure flanking a topological superconducting n…
Chiral magnetic chemical bonds in molecular states of impurities in Weyl semimetals
Y. Marques, W. N. Mizobata, R. S. Oliveira +4
We demonstrate that chirality of the electron scattering in Weyl semimetals leads to the formation of magnetic chemical bonds for molecular states of a pair of impurities. The effe…
Resonant electron tunneling spectroscopy of antibonding states in a Dirac semimetal
Y. Marques, D. Yudin, I. A. Shelykh +1
Recently, it was shown both theoretically and experimentally that certain three-dimensional (3D) materials have Dirac points in the Brillouin zone, thus being 3D analogs of graphen…
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…
Decay of bound states in the continuum of Majorana fermions induced by vacuum fluctuations: Proposal of qubit technology
L. S. Ricco, Y. Marques, F. A. Dessotti +3
We report on a theoretical investigation of the interplay between vacuum fluctuations, Majorana quasiparticles (MQPs) and bound states in the continuum (BICs) by proposing a new ve…
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…
