Reduced Real Space Transformation of Green’s Functions

Motivation:

  • High time and memory requirements are limiting factor in scattering simulations
  • Rank reductions have proven useful in ballistic simulations
  • 20-40 times speedup in NEMO5 using Mil’nikov basis

Approach:

  • Transformation to a position basis so Green’s functions regain position information lost in low rank approximation
  • Transformation to a common basis is required for inelastic scattering in NEGF
