Majorana bound states in the finite-length chain
Recent experiments investigating edge states in ferromagnetic atomic chains on superconducting substrate are analyzed. In particular, finite size effects are considered. It is shown how the energy of the Majorana bound state depends on the length of the chain, as well as on the parameters of the m...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Recent experiments investigating edge states in ferromagnetic atomic chains on superconducting substrate are
analyzed. In particular, finite size effects are considered. It is shown how the energy of the Majorana bound state
depends on the length of the chain, as well as on the parameters of the model. Oscillations of the energy of the
bound edge state in the chain as a function of the length of the chain, and as a function of the applied voltage (or
the chemical potential) are studied. In particular, it has been shown that oscillations can exist only for some values
of the effective potential. |
