SUMMARY:Realistic numerical modeling of Majorana nanowires\, R. G. Her
 b Condensed Matter Seminar\, John Gamble\, Microsoft
DESCRIPTION:Using the Majorana zero modes of one-dimensional systems a
 s topological qubits has recently generated considerable interest\, wi
 th experimental efforts progressing rapidly\, necessitating increasing
 ly intricate qubit encoding schemes and layouts. Moving from a sketch 
 of a complex design to a physical layout is a daunting engineering cha
 llenge\, as small details of the design can have large impacts on devi
 ce operation. Here\, we present a computational tool chain that simula
 tes the physics of these devices from the CAD schematics used for fabr
 ication. By systematically varying the designs\, we perform high-throu
 ghput computations to probe vast swaths of design space. Our simulatio
 ns take into account the physical effects of self-consistent screening
  and superconductivity\, while also including the detailed geometric c
 onfigurations and fringing fields that are critical to device performa
 nce. Finally\, we show validation comparisons with recent experiments 
 in nanowire systems.
