Primes

• Coherence Breakdown Under External Interaction

  • This sourceSystem-bath model of quantum dissipation; macroscopic damping/decoherence from microscopic coupling.

• Damping
  • But in quantum systems, dissipation couples the system to a bath, causing decoherence

    This sourceDevelops quantum dissipation via system–bath coupling (the Caldeira–Leggett model), showing macroscopic damping and decoherence emerging from microscopic coupling.

• Hidden Path and Barrier Crossing
  • The instanton's apparent concreteness can mislead: the path-integral formalism works, but the path is not directly observable.

    This sourceDevelops the theory of quantum dissipation through system-bath coupling (Caldeira-Leggett model); shows how macroscopic damping emerges from microscopic quantum interactions; explains decoherence and loss of quantum coherence in damped systems; bridges quantum mechanics and classical thermodynamics.

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Not recorded. Neither this nor any other of the 3 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.
