Fate of poor man's Majoranas in the long Kitaev chain limit
Melina Luethi, Henry F. Legg, Daniel Loss +1
A minimal Kitaev chain, consisting of two quantum dots connected via a superconductor, can host highly localized near-zero-energy states, known as poor man's Majoranas (PMMs). Thes…

From perfect to imperfect poor man's Majoranas in minimal Kitaev chains
Melina Luethi, Henry F. Legg, Daniel Loss +1
Poor man's Majoranas (PMMs) hold the promise to engineer Majorana bound states in a highly tunable setup consisting of a chain of quantum dots that are connected via superconductor…

Majorana bound states in germanium Josephson junctions via phase control
Melina Luethi, Henry F. Legg, Katharina Laubscher +2
We consider superconductor-normal-superconductor-normal-superconductor (SNSNS) planar Josephson junctions in hole systems with spin-orbit interaction that is cubic in momentum (CSO…
