JAXVacua#

Type IIB flux vacua: complex-structure and axio-dilaton sector, vacuum finding, stability analysis.

JAXVacua is the core flux-vacuum engine of the StringForge ecosystem. It implements the layered pipeline from topological data to flux-vacuum solutions, built natively on JAX with automatic differentiation, just-in-time compilation, and hardware acceleration throughout.

Status#

Public.

What it owns#

  • jaxvacua.lcs.lcs_tree — JAX-registered pytree carrying topological data (Hodge numbers, intersection numbers, GV invariants, conifold info).

  • jaxvacua.periods.periods — period vector, prepotential, Kähler potential at large complex structure.

  • jaxvacua.css.css — Kähler geometry of the complex-structure sector; gauge-kinetic matrix.

  • jaxvacua.flux_eft.FluxEFT — GVW superpotential, F-term scalar potential, D3-tadpole, SL(2,ℤ) duality.

  • jaxvacua.flux_vacua_finder.FluxVacuaFinder — Newton solver, ISD-biased initial-guess sampling, Hessian / mass spectrum via jax.hessian.

  • jaxvacua.flux_bounding.bounded_fluxes — flux enumeration and stochastic search with cluster parallelisation hooks.

  • jaxvacua.sampling.data_sampler — flux / moduli sampling utilities.

  • jaxvacua.freezer — light-field EFTs after integrating out heavy moduli (e.g. conifold freezing).

The full module-by-module breakdown lives in the architecture page.

What it consumes#

  • cytoolsPolytope, Triangulation, Cone for KS-polytope input.

  • jaxpolylogjax_polylog_vmap for the instanton sum.

  • stringforge — for catalog / vacua-vault tooling, end users typically go through stringforge.lcs_database.LCSDatabase rather than constructing models by hand.
