- Coherence Breakdown Under External Interaction
- In the quantum domain, decoherence is the fundamental mechanism: a pure quantum state |ψ⟩ of a system S, initially isolated, becomes entangled with environmental degrees of freedom E through unavoidable interaction channels (thermal radiation, air molecules, electromagnetic noise, measurement apparatus coupling).

Abstract: the apparatus-environment interaction Hamiltonian selects the pointer basis and the environment measures it; it does not state decoherence is fundamental or name the channels.
“The form of the interaction Hamiltonian between the apparatus and its environment is sufficient to determine which observable of the measured quantum system can be considered "recorded" by the apparatus. The basis that contains this record---the pointer basis of the apparatus---consists of the eigenvectors of the operator which commutes with the apparatus-environment interaction Hamiltonian. Thus the environment can …”

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? Read against the text for 1 of 2 citations: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
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.
