New interpretation of the Minkowski limit of gravity
Valerio Faraoni, Luca Gallerani, Alain Maltais-Gosselin +2
It is well-established that the Minkowski limit of pure gravity breaks down, unlike that of full Starobinsky theory . We provide a novel interpretation of…

Dynamics of charged spin- particles in superposed states minimally coupled to electromagnetism in curved spacetime within the WKB approximation
F. Hammad, R. Saadati, M. Simard +1
We investigate the curved-spacetime dynamics of charged spin- particles minimally coupled to the electromagnetic field and propagating in superposed states of differen…

Spin precession and neutrino helicity flip in various spacetimes
Reza Saadati, Fayçal Hammad, Santiago Novoa-Cattivelli +2
We systematically study spin precession of neutral particles freely moving in spacetime. We first derive the formula describing spin precession within a general stationary and axis…
