Signature 01
A sub-percent coherence floor in matter wave interferometry.
PDT predicts a small, specific residual coherence that does not decay to zero in the long arm limit. Standard decoherence theory predicts it does. The deviation lives below one percent and is now within reach of cold atom interferometers.
What a null meansIf the floor is absent at the precision now achievable, the resolution mechanism PDT proposes is wrong.
