Re: [SIESTA-L] problems with the lattice relaxation

2006-07-19 Thread John B. Baba
Dear Siesta user, When I put a Ti adatom on benzene (C6H6)--the initial vertical distance between Ti adatom and the C atom was 2.1Ang, after lattice relaxation, the distance was 2.05 Ang. However, when I changed the initial distance between them to 1.98 Ang, finally I got 1.92 Ang (The only

[SIESTA-L] TO-LO splitting

2006-07-19 Thread Breeze, Jonathan David
Dear Siesta users, I read in the Siesta 2.0 manual that their is a version of 'vibra' that takes into account the TO-LO splitting of phonons developed by Tom Archer at Trinity College in Dubline. I mailed Tom a while ago but have not yet received a reply. Does anyone know if Tom is still active

Dear users, I am trying to use the pdos.f90 code, within Util/pdosxml. But noticed that it is not working for spinpolarized PDOS files. I don't know if there is any line I have to change in m_orbital_chooser.f90. Thanks for your attention. Roberto Hiroki Miwa Brazil.
