This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

The status of experimental tests of general relativity and of theoretical frameworks for
analyzing them is reviewed and updated. Einstein's equivalence principle (EEP) is well …

We discuss the cosmological constant problem in the light of dilatation symmetry and its
possible anomaly. For dilatation symmetric quantum theories realistic asymptotic cosmology …

We briefly summarize motivations for testing the weak equivalence principle and then review
recent torsion-balance results that compare the differential accelerations of beryllium …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

In Einstein's gravitational theory, the spacetime is Riemannian, that is, it has vanishing
torsion and vanishing nonmetricity (covariant derivative of the metric). In the gauging of the …

For centuries the heavens have been a natural laboratory to test the classical laws of motion,
and more recently to test Einstein's theory of gravity. Today, astrophysics has become a vast …

The scalar-tensor theory of gravitation is one of the most popular alternatives to Einstein's
theory of gravitation. This book provides a clear and concise introduction to the theoretical …

The existence of a light or massive scalar field with a coupling to matter weaker than
gravitational strength is a possible source of violation of the weak equivalence principle. We …

Nature's simplest field, the scalar field, has been the protagonist of physical theories for a
long time. Even before the publication of the theory of general relativity G. Nordström …
