An Algebraic Geometry Method for Calculating DOS for 2D tight binding models | Koushik Ray
; Siddhartha Sen
; | Date: |
5 May 2012 | Abstract: | An algebraic geometry method is used to calculate the moments of the electron
density of states as a function of the energy for lattices in the tight binding
approximation. Interpreting the moments as the Mellin transform of the density
allows writing down a formula for the density as an inverse Mellin transform.
The method is illustrated by working out the density function for the
two-dimensional square and honeycomb lattices. | Source: | arXiv, 1205.1122 | Services: | Forum | Review | PDF | Favorites |
