For zero temperature chain (half filling), I use the Hphi to study the MIT of Hubbard model with FullDiag method, but it is found that
the gap (E1-E0) is always zero.
t = -0.5
U=[0, 1, 2, 3, 4, …

For the constrained entanglement research we need a new feature: the ability to calculate the mutual information between sites of the Hubbard model.
This feature has not yet been implemented in GQC…

Eventually it would be great to implement the sqrt(N) depth Trotter steps described in [arXiv:1711.05395](https://arxiv.org/abs/1711.05395) - perhaps @john6060 would be interested in working on this?

Hi, Jutho.
Is it possible to compute fermionic PEPS with `TensorKit`? For example Hubbard model?

Hello,
I was looking through the examples and I saw an example of a periodic hubbard model in an FCIDUMP file, several actually. But I dont undarstant how it is constructed and how the program kno…

Hi, dear developers,
Recently, I used HPhi to calculate a two-dimensional Hubbard model. I have calculated its ground energy and eigenvector. Next, I want to claculate the dynamical Green’s functio…

Hello, thanks for your robust and elegant package!
I'm using this package to perform benchmark of Anderson-Hubbard Model ([ref](https://link.aps.org/doi/10.1103/PhysRevB.81.075106)). It is simply …

From discussing with Joseph Carlson, people want to study a Hubbard model where each site splits up into not only 2 spins, but more. For instance, 3 represents some quark model, 4 some nuclei maybe. W…
