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…
Binary superfluids: Low-energy properties and dissipative processes from spontaneous emission of massive phonons
Silvia Trabucco, Luca Lepori, Maria Luisa Chiofalo +1
We discuss the low-energy properties of binary superfluids with density-dependent interactions. Adding an intra-species coupling that induces an explicit soft symmetry-breaking, we…
A diagrammatic approach to correlation functions in superfluids
Alessia Biondi, Maria Luisa Chiofalo, Massimo Mannarelli +1
Renaud Parentani has given a vast contribution to the development of gravitational analogue models as tools to explore various important aspects of general relativity and of quantu…
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…
