Scattering result asymmetry
|
|
---------------------------
|
|
The lattice scattering code (such as finitesqlatzsym-scattery.py) produces
|
|
asymmetric results where one should not get them, due to the system symmetry.
|
|
|
|
It seems that the asymmetry appears mostly in the y-direction (i.e.
|
|
for example the scattering/absorption cross section at k = (kx, ky, kz)
|
|
is not exactly the same as k = (kx, -ky, kz).
|
|
|
|
What has been checked (hopefully):
|
|
- The flip operators for electric waves
|
|
- Some weird kind of rounding or other numerical error depending on
|
|
the position ordering of the matrix (randomized indices give
|
|
the same asymmetry).
|
|
|
|
What has not been checked (so well):
|
|
- The x,y,z-flip operators for magnetic waves (i.e. are they really
|
|
supposet to bejust the
|
|
same as the operators for electric waves, just with opposite sign?)
|
|
- zplane_pq_y
|
|
- the translation operators
|
|
|
|
|
|
Singular value asymmetry
|
|
------------------------
|
|
Similar as the scattering result asymmetry, although not necessarily
|
|
only in the y-direction?
