I first address the OP's concern about the fact that the dispersion relation is not parabolic. Then I say "different values of 𝑘 label exactly the same wave vector", trying to explain why the same wave vector can have multiple values for energy. Same wave vector, but different $k$. Finally, instead of reposting an earlier post made that has a lot more detail, I pointed to it. | |

It doesn't matter an iota whether you consider the free electron model or the nearly free electron model, in that in both cases one still gets the same feature described by the asker, namely that E(k) yields several values for a single value of k. | |
