Shear viscosity to entropy density ratio: A powerful tool for gravity theories and strongly coupled fluids
Marilù Chiofalo, Dario Grasso, Stefano Liberati +1
In this perspective review, we present a concise yet multifaceted overview of the pivotal role played by the the shear viscosity to entropy density ratio across various physical co…
The gyroscopic frequency of metric and generalised Brans-Dicke theories: constraints from Gravity Probe-B
Abhinandan Dass, Stefano Liberati
We confront the predicted gyroscopic precession (in particular the geodetic precession) from metric theory with the data provided by the mission, Gravity Probe--B. We find t…
Theory of gravitation theories: a no-progress report
Thomas P Sotiriou, Valerio Faraoni, Stefano Liberati
Already in the 1970s there where attempts to present a set of ground rules, sometimes referred to as a theory of gravitation theories, which theories of gravity should satisfy in o…
Analogue spacetime based on 2-component Bose-Einstein condensates
Silke Weinfurtner, Stefano Liberati, Matt Visser
Analogue spacetimes are powerful models for probing the fundamental physical aspects of geometry - while one is most typically interested in ultimately reproducing the pseudo-Riema…
Deformed Special Relativity as an effective theory of measurements on quantum gravitational backgrounds
R. Aloisio, A. Galante, A. Grillo +3
In this article we elaborate on a recently proposed interpretation of DSR as an effective measurement theory in the presence of non-negligible (albeit small) quantum gravitational…
Sonoluminescence as a QED vacuum effect: Probing Schwinger's proposal
S. Liberati, F. Belgiorno, Matt Visser +1
Several years ago Schwinger proposed a physical mechanism for sonoluminescence in terms of photon production due to changes in the properties of the quantum-electrodynamic (QED) va…
