[Smeagol-discuss] About the decimation of states

[Stefano Sanvito]

Hi,

This is well described in several paper describing Smeagol. Please have a look
at:

pin and Molecular Electronics in Atomically-Generated Orbital Landscapes,
Alexandre Reily Rocha, Victor Garcia-Suarez, Steve W. Bailey, Colin J. Lambert,
Jaime Ferrer and Stefano Sanvito, Phys. Rev. B. 73, 085414 (2006)

and also to Alex's thesis at:
