Given a loop's Fourrier coefficients, decide whether the loop has a given symmetry or not.
This would be fairly straightforward if not for the global translation and rotation invariance.
Then, c…

Here is a script which hopefully reproduces an error I am encountering with symmetries. If you're inter…

In the tutorial (and our paper) we implement `MaterialGrid` symmetries using overlapping geometric objects. For some users, this is a bit awkward. Alternatively, one could use the `autograd` (or `jax`…

1. The `YamboStaticScreeningDB` should be improved and tested to better reflect that the database read contains `\sqrt{v}X\sqrt{v}` and not `vX`.
2. Expansion of em1s from IBZ to BZ points using sy…

I would like to extend ACE to allow for representation of $\mathbb{R}^{3\times 3}$ matrix-valued functions, that, besides the standard equivariant symmetry properties, also satisfy symmetries of the f…

Part of #32. Our G&R model creates a tangential stiffness matrix that only has minor and no major symmetries. It thus has `36` unique entries (instead of `21` with major symmetries). I extended `CCTOV…

Elastic constants appear to work more or less out of the box (with one fix), we should probably fix and advertise them in an example. It does take ages to precompile the forward…

Yet another new issue :) I'm just dropping ideas as they come to my mind so that they stay here as possible things to do. I hope you don't mind.
In this case, it is about simmetry. I believe it cou…
