# Large-scale linear system solver using secondary storage: Self-energy in hybrid nanostructures

## Description

Abstract We present a Fortran library which can be used to solve large-scale dense linear systems, A x = b . The library is based on the LU decomposition included in the parallel linear algebra library PLAPACK and on its out-of-core extension POOCLAPACK. The library is complemented with a code which calculates the self-polarization charges and self-energy potential of axially symmetric nanostructures, following an induced charge computation method. Illustrative calculations are provided for hybrid sem...
