Electronic Structure Lab


General interests of the group are understanding the electronic structure of materials using density functional theory. Current interests include charge transfer excitations in donor acceptor complexes (organic photovolatics), linear and non linear polarizabilities of molecules.

Compiling PCM Driver on HPC with Intel Fortran - 2018 Edition (Updated: won't link)

A short note about how to compile PCM library on UTEP-HPC.
Update 7/6/2018 - This approach won't link.

0. Download cmake
Go to https://cmake.org/download/ and download cmake-3.11.0-Linux-x86_64.tar.gz
Extract the tarball file and you have cmake-3.11.0-Linux-x86_64/bin/cmake.
Add this cmake bin directory to your PATH.

1. Log in to HPC VCL
cd PCM2/

15.09 SIC code - FOD Force testing

Comparison of FOD forces from 1509 code against Perfect code.

15.09 SIC Code - Carbon Atom FOD Optimization

FOD optimization of a carbon atom. The geometry is taken from CMU compare directory.

15.09 SIC Code - Energy Testing

Comparison of 15.09 FLO-SIC code against Perfect code. Energies of first and second iterations are compared.
Discrepancy at the first iteration tells you SIC energy calculation is wrong, and discrepancy at the second iteration tells you SIC matrix is calculated wrong.
