Gravitationally mediated entanglement of fermionic qubits: from static to dynamical limits
Moslem Zarei, Mehdi Abdi, Nicola Bartolo +1
We employ the quantum Boltzmann equation to analyze the gravitationally generated entanglement between two remote qubits by considering two explicit microscopic models. A graviton…
Charged Black-Hole Binary Evolution at Second Post-Newtonian Order
Andrea Placidi, Elisa Grilli, Marta Orselli +3
We study the dynamics of electrically charged black-hole binaries and their gravitational-wave emission during the inspiral phase. Within the post-Newtonian framework, we derive th…
Twisted echoes of an odd quartet: Scalar-induced gravitational waves as a probe of primordial parity-violation
H. V. Ragavendra, Nicola Bartolo
Parity-violation leaves tell-tale trails in many cosmological observables. We illustrate parity-odd primordial scalar trispectra, that despite being of modest strength, impart dete…
Inflationary Fossils Beyond Perturbation Theory
Riccardo Impavido, Nicola Bartolo
In this work we provide the missing link between two approaches aimed at characterizing the effect of long perturbation modes in Inflation. We consider the Inflationary Fossils' ap…
Quantum production of gravitational waves after inflation
Alina Mierna, Gabriele Perna, Sabino Matarrese +2
A variety of mechanisms in the early Universe lead to the generation of gravitational waves (GWs). We introduce here a novel source of GWs generated by vacuum fluctuations after in…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Exploring gravitational impulse via quantum Boltzmann equation
Mohammad Sharifian, Moslem Zarei, Nicola Bartolo +1
We investigate the gravitational impulse by using the generalized formulation of the quantum Boltzmann equation (QBE), wherein the initial states are taken as wave packets rather t…
Revisiting the Chern-Simons interaction during inflation with a non-canonical pseudo-scalar
Jun'ya Kume, Marco Peloso, Nicola Bartolo
A Chern-Simons interaction between a pseudo-scalar field and a U(1) gauge field results in the generation of a chiral gravitational wave background. The detection of this signal is…
