Two-site Kitaev sweet spots evolving into topological islands
Rodrigo A. Dourado, J. Carlos Egues, Poliana H. Penteado
Artificial Kitaev chains based on arrays of quantum dots are promising platforms for realizing Majorana Bound States (MBSs). In a two-site Kitaev chain, it is possible to find thes…
Dual topological insulator with mirror symmetry protected helical edge states
Warlley H. Campos, Poliana H. Penteado, Julian Zanon +3
Dual topological insulators (DTIs) are simultaneously protected by time-reversal and crystal symmetries, representing advantageous alternatives to conventional topological insulato…
Nonlocality of local Andreev conductances as a probe for topological Majorana wires
Rodrigo A. Dourado, Poliana H. Penteado, J. Carlos Egues
We propose a protocol based only on local conductance measurements for distinguishing trivial from topological phases in realistic three-terminal superconducting nanowires coupled…
Proximity-induced zero-energy states indistinguishable from topological edge states
Igor J. Califrer, Poliana H. Penteado, J. Carlos Egues +1
When normal metals (NMs) are attached to topological insulators or topological superconductors, it is conceivable that the quantum states in these finite adjacent materials can int…
Spin-orbit coupling in wurtzite quantum wells
J. Y. Fu, P. H. Penteado, D. R. Candido +4
Effective spin-orbit (SO) Hamiltonians for conduction electrons in wurtzite heterostructures are lacking in the literature, in contrast to zincblende structures. Here we address th…
Zitterbewegung and bulk-edge Landau-Zener tunneling in topological insulators
Gerson J. Ferreira, Renan P. Maciel, Poliana H. Penteado +1
We investigate the ballistic zitterbewegung dynamics and the Landau-Zener tunneling between edge and bulk states of wave packets in two-dimensional topological insulators. In bulk,…
