[Pw_forum] How can I extract hopping parameters from the output of wannier90

[Pang Rui]

Dear all
Wannier functions were used in many papers to construct a tight binding
model. The off diaganalization matrix elements were interpreted as the
hopping parameters. However, I found that in most of the times, these
elements were complex numbers. How can I related these complex numbers to
real numbers to parameter a TB model?
 
Best wishes!
