Revisiting the Poor Man's Majoranas: The Spin-Exchange Induced Spillover Effect
J. E. Sanches, T. M. Sobreira, L. S. Ricco +2
We give a review on Poor Man's Majorana (PMM) modes, which are theoretically established in the minimal Kitaev chain implementation consisting of two grounded, spinless quantum dot…
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…
Spin-Exchange Induced Spillover on Poor Man's Majoranas in Minimal Kitaev Chains
J. E. Sanches, L. T. Lustosa, L. S. Ricco +5
The "Poor Man's Majoranas" (PMMs) [Phys. Rev. B 86, 134528 (2012)] devoid of topological protection can "spill over" from one edge into another of the minimal Kitaev chain when per…
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…
