Abstract Chern insulators are two-dimensional magnetic topological materials that conduct electricity along their edges via the one-dimensional chiral modes. The number of these modes is a invariant called first C defines quantized Hall conductance as S x y = e 2 / h . Increasing pivotal for realization low-power-consumption electronics, but there has been no clear-cut solution to this problem ...

This paper is devoted to the analysis of distribution total magnetic quantum number $M$ in a relativistic subshell with $N$ equivalent electrons momentum $j$. analyzed through its cumulants and their generating function, for which an analytical expression provided. function also allows us get values at any order. Such are useful obtain moments various orders. Since distinct subshells additive t...
