Disorder-robust trivial Majorana-like states from smooth confinement in chiral superconducting nanowires
Eslam Ahmed, Jorge Cayao, Yukio Tanaka
Near-zero-energy states in Majorana nanowires can arise from topologically trivial mechanisms such as smooth spatial inhomogeneity and disorder, making zero-energy pinning alone in…

Anomalous proximity effect under Andreev and Majorana bound states
Eslam Ahmed, Yukio Tanaka, Jorge Cayao
We theoretically study the anomalous proximity effect in a ballistic normal metal/diffusive normal metal/superconductor junction based on Rashba semiconductor nanowire model. The s…

Odd-frequency pairing due to Majorana and trivial Andreev bound states
Eslam Ahmed, Shun Tamura, Yukio Tanaka +1
Majorana and trivial Andreev bound states are predicted to appear in superconductor-semiconductor hybrid systems, but their identification is still a challenging task. Here we cons…
