Spontaneous counterflow in rotating supersolids
Silvia Trabucco, Elena Poli, Massimo Mannarelli +1
Rotating supersolids challenge the conventional notion of superfluid flow: quantized vortices coexist with crystalline order arising from the system's intrinsic density modulation.…
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…
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…
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…
Exploring pulsar glitches with dipolar supersolids
Thomas Bland, Francesca Ferlaino, Massimo Mannarelli +2
Glitches are sudden spin-up events that interrupt the gradual spin-down of rotating neutron stars. They are believed to arise from the rapid unpinning of vortices in the neutron st…
Superfluid dark stars
Lorenzo Cipriani, Massimo Mannarelli, Fabrizio Nesti +1
We present a superfluid dark star model consisting of relativistic dark bosons with two-body self-interaction. The obtained masses, radii, and tidal deformability depend in a simpl…
Glitches in rotating supersolids
Elena Poli, Thomas Bland, Samuel J. M. White +4
Glitches, spin-up events in neutron stars, are of prime interest as they reveal properties of nuclear matter at subnuclear densities. We numerically investigate the glitch mechanis…
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…
Phonon emission by acoustic black holes
Massimo Mannarelli, Dario Grasso, Silvia Trabucco +1
We present a novel interpretation of the Hawking temperature of acoustic holes, the hydrodynamic analogue of standard black holes, by connecting the geometrical properties of the h…
Hawking temperature and phonon emission in acoustic holes
Massimo Mannarelli, Dario Grasso, Silvia Trabucco +1
Acoustic holes are the hydrodynamic analogue of standard black holes. Featuring an acoustic horizon, these systems spontaneously emit phonons at the Hawking temperature. We derive…
