Confronting quantum-corrected teleparallel cosmology with observations
  It has been shown that at the semi-classical order, gravitational theories
with quantum fluctuations can be effectively recast as modified theories of
gravity with non-minimal gravity-matter couplings. We proceed from an
observational perspective and see whether such quantum fluctuations can leave
imprints on the late Universe. Within the teleparallel formulation, we
investigate a representative model in this general class of modified
gravitational theories inlaid with quantum fluctuations, and determine the
cosmological parameters by using compiled late-time data sets. Furthermore, we
assess the statistical significance of such quantum corrections compared to the
standard cosmological model. The results mildly favor the inclusion of quantum
corrections with a negative density parameter supporting a phantom-like dark
energy. This edge is not sufficient to rule out either models but it supports
the consideration of quantum corrections in a cosmological setting.
