Domain-specific

• Vacuum Expectation Value
  • A vacuum expectation value (VEV) evaluates a specified operator in a specified quantum-field-theory vacuum.

    This sourceAuthor-hosted lecture notes; locator §3.7 Green's Functions, especially Eqs. (3.294)–(3.295), normalized interacting vacuum and vacuum field-product expectations. https://www.damtp.cam.ac.uk/user/tong/qft/qfthtml/S3.html

  • Zero is a legitimate output; Tong's free-field discussion gives a vanishing field one-point expectation.

    This source(2.98) defines the free vacuum; prose after Eq. (2.127) states the zero field one-point expectation and discusses operator-valued distributions. https://www.damtp.cam.ac.uk/user/tong/qft/qfthtml/S2.html

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
