摘要：

Experimental results on electrical resistance variation with pressure up to 25 GPa are presented for zinc; they reveal the signature of an electronic topological transition. Theoretical estimates based on the results of first-principles band structure calculations corroborate the observed variation of the resistance. The Lifshitz transition, which is hardly observable in experimental P-V data, becomes discernible via the equation of state, in the universal as well as in Holzapfel's form. Another anomaly in the measured resistance is also observed around 20 GPa. pressure. The resistance variation with pressure exhibits considerable hysteresis.
