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…
GW230814: investigation of a loud gravitational-wave signal observed with a single detector
The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783
GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…
Gravitational Waves and Black Hole perturbations in Acoustic Analogues
Chiara Coviello, Maria Luisa Chiofalo, Dario Grasso +3
Phonons in Bose-Einstein condensates propagate as massless scalar particles on top of an emergent acoustic metric. This hydrodynamics/gravity analogy can be exploited to realize ac…
Dissipative processes at the acoustic horizon
Maria Luisa Chiofalo, Dario Grasso, Massimo Mannarelli +1
A transonic fluid flow generates an acoustic hole that is the hydrodynamic analogue of a gravitational black hole. Acoustic holes emit a detectable thermal radiation of phonons at…
