Topologically protected surface Majorana arcs and bulk Weyl fermions in ferromagnetic superconductors
Jay D. Sau, Sumanta Tewari
A number of ferromagnetic superconductors have been recently discovered which are believed to be in the so-called "equal spin pairing" (ESP) state. In the ESP state the Cooper pair…
Majorana fermions in carbon nanotubes
Jay D. Sau, Sumanta Tewari
We show that carbon nanotubes (CNT) are good candidates for realizing one-dimensional topological superconductivity with Majorana fermions localized near the end points. The physic…
Topological invariants for spin-orbit coupled superconductor nanowires
Sumanta Tewari, Jay D. Sau
We show that a spin-orbit coupled semiconductor nanowire with Zeeman splitting and s-wave superconductivity is in symmetry class BDI (not D as is commonly thought) of the topologic…
Experimental and materials considerations for the topological superconducting state in electron and hole doped semiconductors: searching for non-Abelian Majorana modes in 1D nanowires and 2D heterostructures
Jay D. Sau, Sumanta Tewari, S. Das Sarma
In proximity to an s-wave superconductor, a one- or two-dimensional, electron- or hole-doped semiconductor with a sizable spin-orbit coupling and a Zeeman splitting can support a t…
Probing a topological quantum critical point in semiconductor-superconductor heterostructures
Sumanta Tewari, J. D. Sau, V. W. Scarola +2
Quantum ground states on the non-trivial side of a topological quantum critical point (TQCP) have unique properties that make them attractive candidates for quantum information app…
Hole-doped semiconductor nanowire on top of an s-wave superconductor: A new and experimentally accessible system for Majorana fermions
Li Mao, Ming Gong, E. Dumitrescu +2
Majorana fermions were envisioned by E. Majorana in 1935 to describe neutrinos. Recently it has been shown that they can be realized even in a class of electron-doped semiconductor…
