[Kwant] Access to eigenvalue, eigenvector and number of points in each unit cell

[Saj.ZiaBorujeni]

Dear all, 


I need to access to the number of atoms of my unit cell, the eigenvalue and 
eigenvectors for each eigenvalue of my Hamiltonian. 


Is there any one to help me and let me know if it is possible in kwan to access 
them. 


Best wishes, 


Sajad
