• Abstract: In general relativity, the use of conformal transformation is ubiquitous and leads to two different frames of reference, known as the Jordan and the Einstein frames. Typically, the transformation from the Jordan frame to the Einstein frame involves introducing an additional scalar degree of freedom, often already present in the theory. We will show that at the quantum level, owing to this extra scalar degree of freedom these two frames exhibit subtle differences that the entanglement between two massive objects can probe.

• Observation of the quantum equivalence principle for matter-waves [0.06929309810973731]
  Einstein's theory of relativity is based on the principle of equivalence. The equivalence principle involves a gauge phase that is observable if the wavefunction allows an object to interfere with itself. This is done with a novel cold-atom interferometer in which one wave packet stays static in the laboratory frame while the other is in free-fall. We follow the relative-phase evolution of the wave packets in the two frames, confirming the equivalence principle in the quantum domain.

• Quantum Reference Frames for Lorentz Symmetry [0.0]
  We introduce a reformulation of relativistic quantum mechanics independent of any notion of preferred temporal slicing. We define transformations that switch between the perspectives of different relativistic QRFs. We analyse two effects, superposition of time dilations and superposition of length contractions, that arise only if the reference frames exhibit both relativistic and quantum-mechanical features.

• Quantum reference frames and triality [0.0]
  I argue that there may be a symmetry that exchanges the degrees of freedom of the physical frame of reference with the other degrees of freedom which are measured relative to that frame. This symmetry expresses the fact that the choice of frame of reference is arbitrary, but the same laws apply to all, including observer and observed.
