Cosmology with the Laser Interferometer Space Antenna / LISA Cosmology Working Group Collaboration
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 gravitational-wave backgrounds and their implications for early universe and particle physics, from the MeV to the Planck scale. However, the range of potential cosmological applications of gravitational wave observations extends well beyond these two objectives. [...]

New horizons for fundamental physics with LISA / LISA Collaboration
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 gravitational interaction is both strong and dynamical. In this white paper, the Fundamental Physics Working Group of the LISA Consortium summarizes the current topics in fundamental physics where LISA observations of GWs can be expected to provide key input. [...]

Binaries of relatively massive black holes like GW190521 have been proposed to form in dense gas environments, such as the disks of Active Galactic Nuclei (AGNs), and they might be associated with transient electromagnetic counterparts. The interactions of this putative environment with the binary could leave a significant imprint at the low gravitational wave frequencies observable with the Laser Interferometer Space Antenna (LISA).

Unveiling the gravitational universe at $\mu$-Hz frequencies / Sesana, Alberto (Milan Bicocca U.) ; Korsakova, Natalia (Cote d'Azur Observ., Nice) ; Sedda, Manuel Arca (U.

We propose a space-based interferometer surveying the gravitational wave (GW) sky in the milli-Hz to $\mu$-Hz frequency range. By the 2040s', the $\mu$-Hz frequency band, bracketed in between the Laser Interferometer Space Antenna (LISA) and pulsar timing arrays, will constitute the largest gap in the coverage of the astrophysically relevant GW spectrum.

Prospects for Fundamental Physics with LISA / LISA Collaboration
In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental physics. Given the very broad range of topics that might be relevant to LISA, we present here a sample of what we view as particularly promising directions, based in part on the current research interests of the LISA scientific community in the area of fundamental physics.

Constraints on Einstein-Æther theory and Hořava gravity from binary pulsar observations / Yagi, Kent (Montana State U.) ; Blas, Diego (CERN) ; Barausse, Enrico (Paris, Inst. Astrophys.) ; Yunes, Nicolás (Montana State U.)
Binary pulsars are ideal to test the foundations of General Relativity, such as Lorentz symmetry, which requires that experiments produce the same results in all free-falling (i.e.inertial) frames. We here break this symmetry in the gravitational sector by specifying a preferred time direction, and thus a preferred frame, at each spacetime point. [...]

Strong Binary Pulsar Constraints on Lorentz Violation in Gravity / Yagi, Kent (Montana State U.) ; Blas, Diego (CERN) ; Yunes, Nicolás (Montana State U.) ; Barausse, Enrico (Paris, Inst. Astrophys.)
Binary pulsars are excellent laboratories to test the building blocks of Einstein's theory of General Relativity. One of these is Lorentz symmetry which states that physical phenomena appear the same for all inertially moving observers. [...]
