Description
The inflationary paradigm remains the leading candidate for explaining the early universe's homogeneity, isotropy, and the origin of cosmic perturbations. However, its compatibility with current observational data and the persistent tensions within the ÎCDM model motivate the exploration of alternative gravitational frameworks. In this talk, we delve into the dynamics of cosmic inflation within the context of scalar-torsion gravity and its multi-field extensions, specifically within the realm of modified teleparallel gravity. This framework offers a compelling alternative to General Relativity, introducing new gravitational degrees of freedom and modified inflationary dynamics that can lead to distinct predictions for the primordial scalar and tensor power spectra, thereby offering new avenues to address current cosmological tensions.
