A Cartan-geometrical perspective on torsion and non-metricity
Damianos Iosifidis, Tomi Koivisto, Wit Krośnicki +1
Élie Cartan established that the metric and intrinsic curvature of a dimensional embedded manifold could be determined by tracing the response of another surface of the…
Probing the Strong Equivalence Principle through the External Field Effect. How Do Two Masses Fall?
Ankit Kumar, Kelvin Tang Tee Tniam, Peng Chengxiaohe +5
Despite compelling evidence, the absence of a confirmed dark matter particle has sustained interest in modified gravity as an alternative explanation for the observed phenomenology…
On the Bondi accretion of a self-interacting complex scalar field
Dražen Glavan, Alexander Vikman, Tom Zlosnik
Scalar fields with a global U(1) symmetry often appear in cosmology and astrophysics. We study the spherically-symmetric, stationary accretion of such a classical field onto a Schw…
Removing spurious degrees of freedom from EFT of gravity
Dražen Glavan, Shinji Mukohyama, Tom Zlosnik
In the effective field theory approach to gravity, the Lagrangian density for general relativity is supplemented by generally covariant terms of higher order in the Riemann tensor…
Critical reassessment of the restricted Weyl symmetry
Dražen Glavan, Ruggero Noris, Tom Zlosnik
A class of globally scale-invariant scalar-tensor theories have been proposed to be invariant under a larger class of transformations that take the form of local Weyl transformatio…
Sudden cosmological singularities in Aether scalar-tensor theories
João Luís Rosa, Tom Zlosnik
In this work we analyze the possibility of sudden cosmological singularities, also known as type-II singularities, in the background of a Friedmann-Lemaître-Robertson-Walker (FLRW)…
Hamiltonian analysis of metric-affine- theory
Dražen Glavan, Tom Zlosnik, Chunshan Lin
Determining the number of propagating degrees of freedom in metric-affine theories of gravity requires the use of Hamiltonian constraint analysis, except in some subclasses of theo…
Consistent first order action functional for gauge theories
Priidik Gallagher, Tomi S. Koivisto, Luca Marzola +2
A novel first order action principle has been proposed as the possible foundation for a more fundamental theory of General Relativity and the Standard Model. It is shown in this ar…
