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…
Gravitational time dilation in extended quantum systems: the case of light clocks in Schwarzschild spacetime
Tupac Bravo, Dennis Rätzel, Ivette Fuentes
The precision of optical atomic clocks is approaching a regime where they resolve gravitational time dilation on smaller scales than their own extensions. Hence, an accurate descri…
Decay of quantum sensitivity due to three-body loss in Bose-Einstein condensates
Dennis Rätzel, Ralf Schützhold
In view of the coherent properties of a large number of atoms, Bose-Einstein Condensates (BECs) have a high potential for sensing applications. Several proposals have been put forw…
Rotation of polarization in the gravitational field of a laser beam - Faraday effect and optical activity
Fabienne Schneiter, Dennis Rätzel, Daniel Braun
We investigate the rotation of the polarization of a light ray propagating in the gravitational field of a circularly polarized laser beam. The rotation consists of a reciprocal pa…
Dynamical response of Bose-Einstein condensates to oscillating gravitational fields
Dennis Rätzel, Richard Howl, Joel Lindkvist +1
A description of the dynamical response of uniformly trapped Bose-Einstein condensates (BECs) to oscillating external gravitational fields is developed, with the inclusion of dampi…
The gravitational field of a laser beam beyond the short wavelength approximation
Fabienne Schneiter, Dennis Rätzel, Daniel Braun
Light carries energy, and therefore, it is the source of a gravitational field. The gravitational field of a beam of light in the short wavelength approximation has been studied by…
