Re: [Pw_forum] Projected density of state onto isolated molecular orbital

2015-01-30 Thread Guido Fratesi
Dear Xiaochuan Ge, not that directly, but you could possibly prepare a fake atomic_proj.xml file for the molecular part, where the projections of each molecular state are indeed the coefficients of the hybrid orbital over the atomic wavefunctions. If automated, that would also be interesting. Gu

Hi All, Could any of you please confirm me how the colors are chosen in the attached figure? I mean, what is the real meaning (orbital ? ) of the same color, suppose, "blue" ? Delta_5 and Sigma_4 imply two different character of the bands, but still the same "blue" color for both has been used. If

Dear All I wish to calculate optical properties of mono layer of Transition metal di chalcogenides. I believe i have to use TDDFPT i successfully used epsilon.x to calculate imaginary and real part of dielectric function. My question is how to calculate refractive index, Refelectivity, Absorptio

Dear Sohail Ahmad, Note that the current implementation of TDDFPT in Quantum ESPRESSO can be applied only for finite systems, using only a gamma point sampling of the Brillouin zone (K_POINTS {gamma}) and supercells. General k points sampling is not supported in TDDFPT (it is implemented but it

Dear Sohail, Your issue is addressed in a number of standard EM texts, but you may want to have a look at my 1965 PhD thesis on the optical properties of thin germanium films which contains all the relevant algebra, "in reverse," that is, obtaining the dielectric constants from experimental opt

Hi, I am using neb to calculate activation energy of hydrogen in unit cell of nickel. I have placed hydrogen in octahedral position and I am moving it to another octahedral position as shown below. My question is whether neb can calculates transition state which is tetrahedral site?. I have used a
