Probing the Planck scale: the modification of the time evolution operator due to the quantum structure of spacetime
Abstract The propagator which evolves the wave-function in non-relativistic quantum mechanics, can be expressed as a matrix element of a time evolution operator: i.e. G NR(x) = 〈x 2|U NR(t)|x 1〉 in terms of the orthonormal eigenkets |x〉 of the position operator. In quantum field theory, it is not po...
