Frontend

A user-extensible interface to the IR.

  • Inline parser (deserializer)
  • Serializer (tostring method)
  • Batch parser for TOML config file(s)
  • Generic support for n-particle reducibility

Intermediate Representation (IR)

A computational tree representation for generic Feynman diagram(s).

Tree operations

  • Auto-differentiation (e.g., RG flows)
  • Auto-integration (e.g., Matsubara summation for Feynman diagrams and/or general IR trees)

Tree transformations

  • Leaf replacement (subdiagram expansion)
  • Flattening transformation: reduce tree to n layers
  • (Un)distribute transformation: move addition (multiplication) to subdiagram root
  • Filtering transformation: diagram removal based on reducibility rules / custom filter
  • IR to Feynman diagram representation (special case of flatten + distribute transformation)

Backend

Optimization of IR trees and compilation to expression trees. For optimizations, we can either follow or interface with aesara.

Tree optimizations

  • Remove duplicate nodes
  • Merge (combine redundant operations)
  • GEMM optimization for matrix addition/multiplication
  • Support for matrix product states for higher-order vertex functions
