Abstract
The gravitational induced interference is studied here in the framework of teleparallel gravity. We derive the gravitational phase difference and we apply the result to the case of a Kerr spacetime. Afterwards, we compute the fringe shifts in an interference experiment of particles and discuss how to increase their values by changing the given parameters that include the area in between the paths, the energy of the particles, the distance from the black hole, the mass, and the spin of the black hole. It turns out that it is more difficult to detect the fringe shifts for massless particles than for massive particles. As a further application, we show how the mass of the black hole and its angular momentum can be obtained from the measurement of the fringe shifts. Finally, we compare the phase difference derived in teleparallel gravity with a previous work in general relativity.
