ITensor
A package for working with infinite matrix product states (MPS) with ITensor.
The final step I need for my FQHE code is to implement site-dependent QNs. I managed to make it work with a little bit of dirty code on ITensors for...
I'm not sure whether this is expected behavior, but when choosing a large `cutoff` for the subspace expansion (e.g. 10^-3), and a large `maxdim`, the current subspace expansion will still...
Currently, the implementation of VUMPS/TDVP only supports Hamiltonians represented explicitly in terms of sums of local terms (with extensions to long range interactions in #31). Ideally, we would have a...
Follow up to #45. See the discussion https://github.com/ITensor/ITensorInfiniteMPS.jl/pull/45#discussion_r801634815_.
As a follow up to #31, we need to remove some code duplication between serial and parallel update VUMPS. For example, a lot of the code for computing the environments...
For the case I am interested in (FQHE-like Hamiltonians), the local Hamiltonian can be very long range (approximately 15-20 sites would be good to reach). Writing the full local Hamiltonian...
Adapt HDF5 read/write to general `Array{ITensor}` functionality, once https://github.com/ITensor/ITensors.jl/pull/735 is complete.
Some improvements to the VUMPS implementation: - [ ] Use Eq. (22) instead of Eq. (20) in [[1]](https://arxiv.org/pdf/1701.07035.pdf) for updating the left and right orthogonal gauges of the state when...
