We discuss effects of loss of coherence in low energy quantum systems caused by or related
to gravitation, referred to as gravitational decoherence. These effects, resulting from random …

General Relativity is today the best theory of gravity addressing a wide range of phenomena.
Our understanding of physical laws, from cosmology to local scales, cannot be properly …

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

Current attempts to probe general relativistic effects in quantum mechanics focus on
precision measurements of phase shifts in matter–wave interferometry. Yet, phase shifts can …

We report on a precision measurement of gravitational acceleration using ultracold strontium
atoms confined in an amplitude-modulated vertical optical lattice. An uncertainty Δ g/g≈ 10 …

We investigate leading order deviations from general relativity that violate the Einstein
equivalence principle in the gravitational standard model extension. We show that redshift …

Atomic interference experiments can probe the gravitational redshift via the internal energy
splitting of atoms and thus give direct access to test the universality of the coupling between …

Both quantum mechanics and general relativity are based on principles that defy our daily
intuitions, such as time dilation, quantum interference and entanglement. Because the …

Introducing internal-state transitions simultaneously on each branch of a light-pulse atom
interferometer, we propose a scheme that is concurrently sensitive to both violations of the …

We propose a feasible laboratory interferometry experiment with matter waves in a
gravitational potential caused by a pair of artificial field-generating masses. It will …
