vibeqc.run_aiccm2026dev_b_dlpno_mp2(system, basis, mesh=(1, 1, 1), options=None, *, reference=None, dlpno_options=None, aux_basis=None, lattice_cutoff_bohr=15.0, rsgdf_ke_cutoff=200.0, fit_source='auto', rsgdf_tail_ke_cutoff=None, gdf_linear_dep_threshold=1e-09, progress=None, verbose=None)

Run local-PNO MP2 on the exact real representation of the B torus.

The default uses PBC-safe Pipek-Mezey occupied localization. Pair-distance screening and local fitting remain disabled because their current molecular distance definitions are not invariant across a torus boundary.

Parameters:

• system (PeriodicSystem)

• basis (BasisSet)

• mesh (int | Sequence[int])

• options (PeriodicRHFOptions | None)

• reference (object | None)

• dlpno_options (object | None)

• aux_basis (str | None)

• lattice_cutoff_bohr (float)

• rsgdf_ke_cutoff (float)

• fit_source (str)

• rsgdf_tail_ke_cutoff (float | None)

• gdf_linear_dep_threshold (float)

• progress (bool | object | None)

• verbose (int | None)

Return type:

AICCM2026DevBDLPNOMP2Result
