I don't understand why, but `hamil1` and `hamil2` are memorized as `SparseArray`. How did you enter them? `FullSimplify` does not seem to handle sparse arrays. Just apply `Normal` before `Simplify`: Simplify[Normal[hamil1 - hamil2]]

As for why FullSimplify[hamil1-hamil2] is not reducing to a zero matrix, one would need to do either FullSimplify@ComplexExpand[hamil1-hamil2] or FullSimplify@ExpToTrig[hamil1-hamil2] since FullSimplify does not automatically do either of those operations. Your other issue maybe related.
