Quantum and thermal pressures from light scalar fields
Hauke Fischer, Christian Käding, Mario Pitschmann
Light scalar fields play a variety of roles in modern physics, especially in cosmology and modified theories of gravity. For this reason, there is a zoo of experiments actively try…
Screened Scalar Fields in the Laboratory and the Solar System
Hauke Fischer, Christian Käding, Mario Pitschmann
The last few decades have provided abundant evidence for physics beyond the two standard models of particle physics and cosmology. As is now known, the by far largest part of our u…
Dynamical Casimir effect with screened scalar fields
Ana Lucía Báez-Camargo, Daniel Hartley, Christian Käding +1
Understanding the nature of dark energy and dark matter is one of modern physics' greatest open problems. Scalar-tensor theories with screened scalar fields like the chameleon mode…
Search for dark energy with neutron interferometry
Hauke Fischer, Christian Käding, Hartmut Lemmel +2
We use previously obtained experimental results by neutron interferometry to effectively constrain the parameter space of several prominent dark energy models. This investigation e…
