Zero-bias peaks in spin-orbit coupled superconducting wires with and without Majorana end-states
Jie Liu, Andrew C. Potter, K. T. Law +1
One of the simplest proposed experimental probes of a Majorana bound-state is a quantized (2e^2/h) value of zero-bias tunneling conductance. When temperature is somewhat larger tha…
Quantum spin liquids and the metal-insulator transition in doped semiconductors
Andrew C. Potter, Maissam Barkeshli, John McGreevy +1
We describe a new possible route to the metal-insulator transition in doped semiconductors such as Si:P or Si:B. We explore the possibility that the loss of metallic transport occu…
Hanbury-Brown and Twiss interference of anyons
Gabriele Campagnano, Oded Zilberberg, Igor V. Gornyi +3
We present a study of an Hanbury Brown and Twiss (HBT) interferometer realized with anyons. Such a device can directly probe entanglement and fractional statistics of initially unc…
Topological Superconductivity and Majorana Fermions in Metallic Surface-States
Andrew C. Potter, Patrick A. Lee
Heavy metals, such as Au, Ag, and Pb, often have sharp surface states that are split by strong Rashba spin-orbit coupling. The strong spin-orbit coupling and two-dimensional nature…
