### Peer-reviewed applications and observable-level validation

A learned Hamiltonian is an input to a physical calculation, not a guarantee
that every downstream observable is accurate. These published studies give
distinct examples of how electronic-structure models are connected to and
validated against physical properties:

Qualify how SLEM models the overlap matrix.

Line 59 groups the Hamiltonian, overlap, and density matrices under one rotation-equivariant representation. The ICLR paper uses SLEM’s equivariant representation for the Hamiltonian and density matrix, but fits the overlap through invariant two-center Slater–Koster scalars. State this distinction so the table describes the overlap parameterization accurately. (proceedings.iclr.cc)

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Review comment at @README.md at line 59:
Update the README table entry to distinguish SLEM’s equivariant representation
for the Hamiltonian and density matrices from its overlap parameterization using
invariant two-center Slater–Koster scalars.

These are **different model, material and validation settings**, not interchangeable
performance claims. For device-level transport, see the separate
[DPNEGF solver](https://github.com/deepmodeling/dpnegf); the DeePTB model
does not by itself include electrode self-energies, gate electrostatics or
full device transport.
