  Pressure-induced changes in the Fermi surface of Cd up to 40 GPa are studied
using highly accurate density-functional theory calculations. The topology of
Fermi surface changes at pressures of 2, 8, 12 , 18 and 28 GPa indicating
electronic topological transitions (ETTs). Structural parameters,
compressibility data and elastic constant reveal anomalies across these ETTs.
The computed equation of state at 300 K is in excellent agreement with the
experimental data. In view of the highly controversial nature of these ETTs the
present studies are aimed at motivating the experimentalists for their direct
detection at high pressures.
