Gravitational attraction of ultra-relativistic matter: A new testbed for modified gravity at the Large Hadron Collider
Christian Pfeifer, Dennis Rätzel, Daniel Braun
We derive the scalar-tensor modification of the gravitational field of an ultrarelativistic particle beam and its effect on a test particle that is used as sensor. To do so, we sol…

Non-linear media in weakly curved spacetime: optical solitons and probe pulses for gravimetry
Alessio Belenchia, Felix Spengler, Dennis Rätzel +1
That light propagating in a gravitational field gets frequency-shifted is one of the basic consequences of any metric theory of gravity rooted in the equivalence principle. At the…
