Theory 12/Ultralight dark matter/Quantum sensors
Dark Matter Is a Coherent Field
The claim
Ultralight dark matter would appear as an oscillating field rather than as particles, with a coherence time set by the ratio of its mass to its velocity dispersion.
01Mechanism
A field with a tiny mass oscillates at a fixed frequency; its velocity spread limits how long the oscillation stays in phase.
02Prediction
A signal should appear as a peak whose width is set by velocity dispersion.
03Refutation
No narrowband peak at achievable sensitivity would constrain the field interpretation.
04What makes it checkable
Precision magnetometers and optomechanical sensors now have the sensitivity to detect the narrowband oscillation a coherent field would produce.
05Why it was not testable before
The predicted coupling is far below earlier detector noise floors.
