• Hole superconductivity
• Chapnik's rule
• Brillouin zone effects

We predict that simple metals and early transition metals that become superconducting under high pressures will show a change in sign of their Hall coefficient from negative to positive under pressure. If verified, this will strongly suggest that hole carriers play a fundamental role in 'conventional' superconductivity, as predicted by the theory of hole superconductivity.
