[Wien] fold2Bloch: new add-on for calculation of the band structure of supercells

2014-06-06 Thread Oleg Rubel
Dear Wien2k Community: I am glad to announce a new tool for studying the electronic structure of disordered solids. It enables "unfolding" of the band structure of supercells back to its conventional (Bloch) representation. For example, it can be useful for visualizing the band structure of compou

I think case.engre might be created by BoltzTraP when it is ran with CALC in case.intrans [http://www.mail-archive.com/wien%40zeus.theochem.tuwien.ac.at/msg04755.html]. On 6/6/2014 7:06 AM, idris.09 idris wrote: Dear Wien2k users I am having a problem in running boltztrap. i have installed t

Dear Wien2k users I am having a problem in running boltztrap. i have installed the code and the test runs are also running without any problem. when i tried to run boltztrap i got the following error At line 132 of file m_bandstructure.F90 (unit = 48, file = 'Rumn.engre') Fortran runtime error:

If there are no in1c, in2c etc files after the initialisation then the structure has most probably an inversion center and does not need a complex calculation or something else went wrong during initialisation and the creation of the in1, in2 etc files was not even started. In my experience "th

Hi, according to my understanding, the box "complex calculation (no inversion)" is useless and misleading. One should never select it even if there is no inversion in the solid. So, do everything without selecting "complex ...". During initialization, WIEN2k will automatically determine if there

Dear users: I want to do a no inversion caculation, and I select the "complex calculation (no inversion) "function at the begining session. Then I follow the w2web step by step until to the "x dstart" function, But there is no case.in1c and case.in2c produced, then the "x dstart"

If SOC is included, I cannot see any other reason for the 4-fold degeneracy than an accidental one. The presence of the inversion operation is already taken into account when considering the irreps. In relation with the other comment received, I think that the relationship of the parity of the

You say that you don't have inversion symmetry, however, D3d has inversion symmetry (see your first e-mail) Just some remarks from the reference given by irrep: Table 55 on page 58 in Koster et al [7] D3d = D3 x Ci even (+) and odd (-) parity mean even = s, d, g and odd = p, f, ... angular
