Figure 1

Phonon dispersion of vanadium along high symmetry directions, at ambient pressure (open black symbols4), 11 GPa (red symbols) and 26 GPa (purple symbols) at ambient temperature.

Circles denote LA modes, squares and triangles (when not degenerate) denote TA modes. For clarity errors bars (between 0.1 and 1.2 meV) are not shown. The lines through the experimental points are guides to the eye.
