abstract = {The symmetry of the material is an important factor
determining its properties. In this work, we demonstrate
both experimentally and by numerical simulations that the
actual symmetry of the rutile phase of TiO$_2$ is
orthorhombic, described with space group $Pnnm$, in contrast
to what it is commonly believed that rutile TiO$_2$ has a
tetragonal symmetry, described with space group $P4_2/mnm$.
We present very precise first-principles calculations for
the determination of the structural properties of rutile
TiO$_2$ and highlight the relevance of using the revised
regularized SCAN meta-GGA density functional for the
interpretation and analysis of neutron and synchrotron
radiation diffraction measurements. The lowering of the
symmetry has a small but not negligible influence on the
elastic, vibrational, and optical properties of rutile
TiO$_2$.},
