Adiabatic manipulations of Majorana fermions in a three-dimensional network of quantum wires
Bertrand I. Halperin, Yuval Oreg, Ady Stern +3
It has been proposed that localized zero-energy Majorana states can be realized in a two-dimensional network of quasi-one-dimensional semiconductor wires that are proximity-coupled…
Manipulating Majorana fermions using supercurrents
Alessandro Romito, Jason Alicea, Gil Refael +1
Topological insulator edges and spin-orbit-coupled quantum wires in proximity to s-wave super- conductors can be tuned through a topological quantum phase transition by a Zeeman fi…
Unconventional Josephson signatures of Majorana bound states
Liang Jiang, David Pekker, Jason Alicea +3
A junction between two topological superconductors containing a pair of Majorana fermions exhibits a `fractional' Josephson effect, periodic in the superconductors' phase diff…
Deformed triangular lattice antiferromagnets in a magnetic field: role of spatial anisotropy and Dzyaloshinskii-Moriya interactions
Christian Griset, Shane Head, Jason Alicea +1
Recent experiments on the anisotropic spin-1/2 triangular antiferromagnet Cs_2CuBr_4 have revealed a remarkably rich phase diagram in applied magnetic fields, consisting of an unex…
Interaction Effects in Topological Superconducting Wires Supporting Majorana Fermions
E. M. Stoudenmire, Jason Alicea, Oleg A. Starykh +1
Among the broad spectrum of systems predicted to exhibit topological superconductivity and Majorana fermions, one-dimensional wires with strong spin-orbit coupling provide one of t…
Engineering a robust quantum spin Hall state in graphene via adatom deposition
Conan Weeks, Jun Hu, Jason Alicea +2
The 2007 discovery of quantized conductance in HgTe quantum wells delivered the field of topological insulators (TIs) its first experimental confirmation. While many three-dimensio…
