On the Testability of the Equivalence Principle as a Gauge Principle Detecting the Gravitational t3 Phase
There have been various claims that the Equivalence Principle, as originally formulated by Einstein, presents several difficulties when extended to the quantum domain, even in the regime of weak gravity. Here we point out that by following the same approach as used for other classical principles, e.g. the principle of …
