EXACTLY SOLVABLE MODEL OF TOPOLOGICAL TRANSITIONS IN METALS

Abstract

In this paper, we consider ETP using a precisely solvable model of an electron in a crystal. The main characteristics of the transition are given by analytical functions that contain only the parameters of the potential. The results of calculations are compared with experimental data on the Lifshitz phase transition (genus transition) in normal metals. The practical significance of the work is to increase the accuracy of quantitative predictions of the physical properties of alloys of various transition metals.
