    • This discussion applies to the tensile case also, where (Formula presented) and (Formula presented) should be set equal to zero. At the end of the last paragraph we however did not use this argument to generate the eigenspectrum because the 1D unit cell length simply scales as (Formula presented) The essence of this discussion is that if the change in hopping parameters is accounted for, then the eigenspectrum can be calculated by assuming that the geometry has not changed.
