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…

State-Agnostic Approach to Certifying Electron-Photon Entanglement in Electron Microscopy
Phila Rembold, Santiago Beltrán-Romero, Alexander Preimesberger +6
Transmission electron microscopes (TEMs) enable atomic-scale imaging and characterisation, driving advances across fields from materials science to biology. Quantum correlations, s…
