DOI: 10.1088/1361-6382/adc06e
Abstract: We analyze scalar field dark energy models minimally and non-minimally coupled to gravity, postulating that a Yukawa-like interacting term is in form equivalent for general relativity, teleparallel and symmetric-teleparallel theories. Our analysis is pursued within… read more here.

DOI: 10.1088/1475-7516/2018/04/041
Abstract: In this work we present a generalized Brans-Dicke lagrangian including a non-minimally coupled Gauss-Bonnet term without imposing the vanishing torsion condition. In the resulting field equations, the torsion is closely related to the dynamics of… read more here.

Abstract: We probe the spectrum of primordial gravitational waves (GWs) produced during the eras of hyperkination, kination, and reheating in a non-minimally coupled, ℒ ∝ (1 + ξχ/M Pl) t (R + αR 2), modified gravity… read more here.

DOI: 10.1088/1475-7516/2025/08/083
Abstract: The most recent data release from the Atacama Cosmology Telescope (ACT) reveals a larger value of the scalar spectral tilt n_s, ruling out a broad class of inflationary attractors. In this paper, we consider inflationary… read more here.

DOI: 10.1088/1475-7516/2025/11/067
Abstract: We explore a cosmological model in which dark matter is non-minimally coupled to gravity at the fluid level. While typically subdominant compared to Standard Model forces, such couplings may dominate dark matter dynamics. We show… read more here.

DOI: 10.1140/epjc/s10052-020-08723-z
Abstract: It has recently been revealed that massless scalar fields which are non-minimally coupled to the Maxwell electromagnetic tensor can be supported in the exterior spacetime regions of spherically symmetric charged black holes. The boundary between… read more here.

DOI: 10.1186/s13063-024-08375-4
Abstract: Currently, non- or minimally displaced distal radius fractures are treated by 3 to 5 weeks of cast immobilisation. Many patients with a distal radius fracture suffer from long-term functional restrictions, which might be related to… read more here.
