13 hours ago · [citation needed] Any candidate theory of quantum gravity must be able to reproduce Einstein's theory of general relativity as a classical limit of a quantum theory. This is not guaranteed because of a feature of quantum field theories which is that they have different sectors, these are analogous to the different phases that come about in the ...
13 hours ago · The GPS implements two major corrections to its time signals for relativistic effects: one for relative velocity of satellite and receiver, using the special theory of relativity, and one for the difference in gravitational potential between satellite and receiver, using general relativity.

May 3, 2024 · Thus, the electron density has the desirable property of being an experimental observable (Eq. ) and, at the same time, a quantity that is readily calculated from quantum chemical theory (Eq. ). This accessibility from theory via the wavefunction and from experiment after phasing the structure factors may be represented symbolically as:
13 hours ago · This theory extends general relativity by removing a constraint of the symmetry of the affine connection and regarding its antisymmetric part, the torsion tensor, as a dynamical variable. The minimal coupling between torsion and Dirac spinors generates a spin-spin interaction that is significant in fermionic matter at extremely high densities.
