Cascaded Optomechanical Sensing for Small Signals
Marta Maria Marchese, Daniel Braun, Stefan Nimmrichter +1
We propose a sensing scheme for detecting weak forces that achieves Heisenberg-limited sensitivity without relying on entanglement or other non-classical resources. Our scheme util…
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…
The path towards measuring the gravitational field of proton bunches at accelerators
Daniel Braun, Rongrong Cai, Pascal Hermes +6
The Newtonian law describing the gravitational interaction of non-relativistic (slowly moving) gravitating matter, has been tested in many laboratory experiments with very high pre…
Metrology of Gravitational Effects with Mechanical Quantum Systems
Daniel Braun, Marta Maria Marchese, Stefan Nimmrichter +3
Mechanical quantum systems, such as resonators and levitated particles, offer unique opportunities for quantum metrology. Particularly, their significant mass and quantum-level con…
