Three principles for canonical quantum gravity - Philsci
... ory of gravity should depend on background structures therefore space-time dieomorphism invariance needs to be implemented. The history of how we ended up with background independence as a principle throughout the history of physics all the way back to the relational ideas of Mach is well recounted ...

Does quantum field theory exist? Final Lecture
... simply push on as if we had not just had premonitions of disaster. Thus we are given an irreducible representation of the relations (7) on a Hilbert space H. The arguments we have given for deriving the form of the quantum Hamiltonian H (by way of Ehrenfest’s theorem, for example) are still valid he ...

Mobile quantum gravity sensor with unprecedented stability
... The gravimetric atom interferometer GAIN is based on interfering ensembles of laser-cooled 87 Rb atoms in a fountain setup, using stimulated Raman transitions. GAIN’s rugged design allows for transports to sites of geodetic and geophysical interest while maintaining a high accuracy compatible with t ...

Open Questions in Physics

... An aggregate of mutually unbiased bases is a set of orthonormal bases which are pairwise mutually unbiased. It has been found that the maximum number of such bases cannot be greater than d + 1 in d-dimensional Hilbert space [Wootters & Fields, 1989). It is also known that this limit is reached if d ...

(2+ 1)-Dimensional Chern-Simons Gravity as a Dirac Square Root
... This condition picks out a connected component in the space of holonomy groups, and Mess [11] has shown that any group lying in this component corresponds to a solution of the field equations. (See also [12] for a description geared more towards physicists, and [13] for a closely related lattice app ...
