I want to share some initial thoughts that I think are part of a larger discussion we should have about which design patterns should be preferred when providing functions to...
Our library currently contains code to generate molecular electronic structure Hamiltonians in 2D in the plane wave and dual bases. Such Hamiltonians are interesting in some contexts, for instance jellium...
Plane waves are periodic basis functions. If one tries to use them to simulate systems of reduced periodicity (i.e. periodic in two-dimensions like graphene, one-dimension like a polymer, or zero-dimensions...
Pull request #221 starts a comprehensive list of features which we will merge once completed (help on that welcome, especially if making additions which explain your contribution). This should help...
@TariniHardikar @kanavsetia @hsim13372 @jarrodmcc Now that we have the alpha version of our cloud library up and running (thanks again to @Spaceenter who did a lot of work on this)...
[arXiv:1502.04698](https://arxiv.org/abs/1502.04698) describes a method for "folding" correlations from Hamiltonians in larger basis sets into Hamiltonians in smaller basis sets. Thus, this is a method for obtaining minimal basis sets with...
Perturbative gadgets are techniques for manipulating representations of qubit Hamiltonians which would be very useful in some contexts. They are particularly interesting in the context of quantum simulation and multiple...
Schemes such as Dynamical Mean-Field Theory (DMFT) or Density Matrix Embedding Theory (DMET), to name just two ideas from a larger family, allow one study the properties of a much...
There are tools such as VMD and Avogadro which are designed to visualize molecular orbitals and charge densities. Thus, one should be able to use these tools to visualize the...
Explained in [this 2005 paper](https://arxiv.org/abs/cond-mat/0508353) by Verstraete and Cirac, it is possible to transform local fermion Hamiltonians on a lattice in D dimensions into local spin Hamiltonians on a lattice...
