Good night all MPB user
I want to ask about how to define block in MPB
I try to define triangular lattice structure by MPB, with block as basis
but I do not now how to get the usual block. When I define e1,e2,e3 like following
(e1 0.5 0.5 0) (e2 0.866 -0.866 0)
I get thee rotated block rather than usual block. Please tell me how to define the block and why I use lattice vector
(basis1 (/ (sqrt 3) 2) 0.5)
(basis2 (/ (sqrt 3) 2) -0.5).
Another thing I want to know is, if there is a way in MPB to get the k-point of band calculation in x-y basis, not reciprocal lattice basis.This is a problem when I try to get EFS
Thank you for the guidance
Andika A
