The exploration of the universe has recently entered a new era thanks to the multi-
messenger paradigm, characterized by a continuous increase in the quantity and quality of …

Analogue gravity is a research programme which investigates analogues of general
relativistic gravitational fields within other physical systems, typically but not exclusively …

We present an updated review of Lorentz invariance tests in effective field theories (EFTs) in
the matter as well as in the gravity sector. After a general discussion of the role of Lorentz …

I review the current status of phenomenological programs inspired by quantum-spacetime
research. I stress in particular the significance of results establishing that certain data …

Hořava's proposal for non-relativistic quantum gravity introduces a preferred time foliation of
space-time which violates the local Lorentz invariance. The foliation is encoded in a …

Based on string theory, black hole physics, doubly special relativity and some'thought'
experiments, minimal distance and/or maximum momentum are proposed. As alternatives to …

We review the main theoretical motivations and observational constraints on Planck scale–
suppressed violations of Lorentz invariance. After introducing the problems related to the …

Stringent limits on the Myers-Pospelov timelike parameter for photons ξ< 10-15 coming from
astrophysical tests suggest exploring more general preferred backgrounds, such as …

Parameterizing hypothetical violation of Lorentz invariance at high energies using the
framework of effective quantum field theory, we discuss its effect on the formation of …

The CPT-even gauge sector of the standard model extension is composed of 19
components comprised in the tensor (KF) μ ν ρ σ, of which nine do not yield birefringence. In …
