Impact of Broken Inversion Symmetry on Molecular States in multi-Weyl fermions
W. C. Silva, J. E. Sanches, D. S. Rojo +6
We study inversion-symmetry (IS) breaking in impurity dimers coupled to topological multi-Weyl systems in the low-energy dispersion domain. In the IS-preserved multi-Weyl semimetal…
Squeezed state protection of fine structure in "Poor Man's Majorana" via quantum spin coupling
J. E. Sanches, L. T. Lustosa, L. S. Ricco +5
The "Poor Man's Majorana" [Phys. Rev. B 86, 134528 (2012)] devoid of topological protection has been theoretically predicted to rely on the minimal Kitaev chain. Afterward, a pair…
Analogue of atomic collapse for adatoms on rhombohedral multilayer graphene
W. C. Silva, J. E. Sanches, A. M. Freitas +3
We propose that a multi-graphene of ABC-type stacking yields virtual bound states lying within the Coulomb insulating gap of an Anderson-like adatom. Wondrously, a virtual state co…
Fractionalization of Majorana-Ising-type quasiparticles
J. E. Sanches, L. T. Lustosa, L. S. Ricco +4
We theoretically investigate the spectral properties of a quantum impurity (QI) hosting the here proposed {Majorana-Ising-type quasiparticle (MIQ) excitation}. It arises from the c…
Topological charge Fano effect in multi-Weyl semimetals
W. C. Silva, W. N. Mizobata, J. E. Sanches +6
We theoretically analyze the Fano interference in a single impurity multi-Weyl semimetal hybrid system and show the emergence of the topological charge Fano effect in the bulk loca…
Atomic frustration-based twistronics
W. N. Mizobata, J. E. Sanches, M. Penha +5
We theoretically investigate atomic frustrated states in diatomic molecules hosted by the bilayer graphene setup twisted by the first magic angle and with broken inversion symmetry…
