Dynamical Cosmological Constant
Giuseppe di Donato, Luigi Pilo
The dynamical realisation of the equation of state is studied. A non-pathological dynamics for the perturbations of such a system mimicking a dynamical cosmological consta…
The Physical Content of Long Tensor Modes in Cosmology
Nicola Bartolo, Giovanni Battista Carollo, Sabino Matarrese +2
We analyze the physical content of squeezed bispectra involving long-wavelength tensor perturbations, showing that these modes cannot be gauged away, except for the exact (unphysic…
Classical and Quantum Dynamics of Gyroscopic Systems and Dark Energy
Denis Comelli, Maicol Di Giambattista, Luigi Pilo
Gyroscopic systems in classical and quantum field theory are characterized by the presence of at least two scalar degrees of freedom and by terms that mix fields and their time der…
New Horizons for Fundamental Physics with LISA
K. G. Arun, Enis Belgacem, Robert Benkel +138
The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders about the fundamental theory of nature at play in the extreme gravity regime, where the gravitatio…
Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Quantum Corrections to the Stochastic Gravitational Wave Background
Denis Comelli, Maicol Di Giambattista, Luigi Pilo +1
We study 1-loop corrections to the primordial stochastic background of gravitational waves produced during inflation. While in single-clock, at the leading order in slow-roll, quan…
