Most embeddings of the Standard Model into a more unified theory, in particular those
based on supergravity or superstrings, predict the existence of a hidden sector of particles …

We review recent mechanical experiments that test some of the most basic principles of
physics including the weak and strong forms of the Equivalence Principle, the gravitational …

We investigate the potential of the warped extradimension framework as an explanation for
the recently observed stochastic gravitational background at nHz frequencies in pulsar …

We tested the gravitational 1/r 2 law using a stationary torsion-balance detector and a
rotating attractor containing test bodies with both 18-fold and 120-fold azimuthal symmetries …

The subject of this book is the Casimir effect, a manifestation of zero-point oscillations of the
quantum vacuum resulting in forces acting between closely spaced bodies. For the benefit of …

We conducted three torsion-balance experiments to test the gravitational inverse-square law
at separations between 9.53 mm and 55 μ m, probing distances less than the dark-energy …

We demonstrate that short-period stars orbiting around the supermassive black hole in our
Galactic center can successfully be used to probe the gravitational theory in a strong regime …

The pure-gravity sector of the minimal standard-model extension is studied in the limit of
Riemann spacetime. A method is developed to extract the modified Einstein field equations …

Quality factor (Q) is an important property of micro-and nano-electromechanical (MEM/NEM)
resonators that underlie timing references, frequency sources, atomic force microscopes …

A bstract We show that the relaxion generically stops its rolling at a point that breaks CP
leading to relaxion-Higgs mixing. This opens the door to a variety of observational probes …
