Dear Siesta Users,
We are currently studying charged defects in bulk materials with
SIESTA. In the case of such systems, the total energies obtained must
be usually treated with care and a number of corrections can be
applied. My question is about the way SIESTA accounts for these
Dear Siesta Users,
I tried to obtain optical spectra for the crystal with 468 atoms in the
unit cell, but the corresponding job was aborted with the communication
Error in Cholesky factorisation in cdiag in the end of output file.
Please, advise me how I could solve the problem. Thanks in
Hi Julie,
For solids:
There is a paper by Ambrosch-Draxl on calculating the optical
properties of solids (In the FP-LAPW basis). The third and fourth
pages are relevant though:
