Query: Reliable lattice dynamics from an efficient density functional   First principles predictions of lattice dynamics are of vital importance for
a broad range of topics in materials science and condensed matter physics. The
large-scale nature of lattice dynamics calculations and the desire to design
novel materials with distinct properties demands that first principles
predictions are accurate, transferable, efficient, and reliable for a wide
variety of materials. In this work, we demonstrate that the recently
constructed r2SCAN density functional meets this need for general systems by
demonstrating phonon dispersions for typical systems with distinct chemical
characteristics. The functional's performance opens a door for phonon-mediated
materials discovery from first principles calculations.
