Strong localization of Majorana end states in chains of magnetic adatoms
Yang Peng, Falko Pientka, Leonid I. Glazman +1
A recent experiment [Nadj-Perge et al., Science 346, 602 (2014)] gives possible evidence for Majorana bound states in chains of magnetic adatoms placed on a superconductor. While m…
Topological properties of linear circuit lattices
Victor V. Albert, Leonid I. Glazman, Liang Jiang
Motivated by the topologically insulating (TI) circuit of capacitors and inductors proposed and tested in arXiv:1309.0878, we present a related circuit with less elements per site.…
Experimental evidence and control of the bulk-mediated intersurface coupling in topological insulator Bi2Te2Se nanoribbons
Zhaoguo Li, Ion Garate, Jian Pan +14
Nearly a decade after the discovery of topological insulators (TIs), the important task of identifying and characterizing their topological surface states through electrical transp…
Resistance of helical edges formed in a semiconductor heterostructure
Jukka I. Väyrynen, Moshe Goldstein, Yuval Gefen +1
Time-reversal symmetry prohibits elastic backscattering of electrons propagating within a helical edge of a two-dimensional topological insulator. However, small band gaps in these…
