### Description
In some cases (see e.g. #7734) derivatives are involved in nonlinear strong components. If not solved with the appropriate precision, they may fool the ODE solvers's error control m…

Thoughts after questions from AmpLab staff Jey Kottalam:
So far we have been providing analytical expressions for the 4th spatial derivatives for the covariance kernel, it is possible for us to explor…

We use numerical derivatives in the MBTR to get forces, which is slow. You can use the ones from MBTR, and there's [an example showing how to do so](https://singroup.github.io/dscribe/latest/tutorials…

tl;dr: While JAX clamps indices to the array bounds when evaluating array indexing operations, the same logic does not appear to be applied when back-propagating derivatives through the indexing opera…

Even after #5077 fixed a bug with higher-order derivatives of `jnp.sinc` _at_ zero, there remains a numerical stability issue with 4th and higher derivatives _near_ zero:
