Relativistic Astronomy. III. Test of Special Relativity via Doppler Effect

, 2019
The Breakthrough Starshot program is planning to send transrelativistic probes to travel to nearby stellar systems within decades. Because the probe velocity is designed to be a good fraction of the light speed, Zhang & Li recently proposed that these ...

Foundations of Quantum Gravity : The Role of Principles Grounded in Empirical Reality [PDF]

, 2014
When attempting to assess the strengths and weaknesses of various principles in their potential role of guiding the formulation of a theory of quantum gravity, it is crucial to distinguish between principles which are strongly supported by empirical data

The Equivalence Principle Revisited [PDF]

, 2002
A precise formulation of the strong Equivalence Principle is essential to the understanding of the relationship between gravitation and quantum mechanics.

Overlooked effects of wavefront reception with or without speed limit, from aberration to time measurement

Results in Optics
A general approach to wavefront reception applicable to any type of wave allows to point out some overlooked aspects and ignored consequences of established theories.

Recent Experimental Tests of Special Relativity

, 2005
We review our recent Michelson-Morley (MM) and Kennedy-Thorndike (KT) experiment, which tests Lorentz invariance in the photon sector, and report first results of our ongoing atomic clock test of Lorentz invariance in the matter sector.

Was Einstein Right? Testing Relativity at the Centenary

, 2005
We review the experimental evidence for Einstein's special and general relativity. A variety of high precision null experiments verify the weak equivalence principle and local Lorentz invariance, while gravitational redshift and other clock experiments ...

The Physical Role of Gravitational and Gauge Degrees of Freedom in General Relativity - I: Dynamical Synchronization and Generalized Inertial Effects [PDF]

, 2004
This is the first of a couple of papers in which, by exploiting the capabilities of the Hamiltonian approach to general relativity, we get a number of technical achievements that are instrumental both for a disclosure of \emph{new} results concerning ...

Test of Time Dilation Using Stored Li+ Ions as Clocks at Relativistic Speed

, 2014
We present the concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of beta = v/c = 0.338 in the storage ring ESR at Darmstadt. A Lambda-type three-level system within the hyperfine structure of the

On Locality in Quantum General Relativity and Quantum Gravity [PDF]

, 1996
The physical concept of locality is first analyzed in the special relativistic quantum regime, and compared with that of microcausality and the local commutativity of quantum fields. Its extrapolation to quantum general relativity on quantum bundles over

Observers' measurements in premetric electrodynamics I: Time and radar length

, 2018
The description of an observer's measurement in general relativity and the standard model of particle physics is closely related to the spacetime metric. In order to understand and interpret measurements, which test the metric structure of the spacetime,
