The calculations show that three electronic topological transitions (ETT's) occur in Zn when the $c/a$ axial ratio diminishes under compression. One transition occurs at $c/a\ensuremath{\simeq}1.82$ when the ``needles'' appear around the symmetry point K of the Brillouin zone. The other two transitions occur at $c/a\ensuremath{\simeq}\sqrt{3},$ when the ``butterfly'' and ``cigar'' appear simultaneously both around the L point. It has been shown that these ETT's are responsible for a number of anomalies observed in Zn at compression.Read More
