Breaking changes (new lattice, measurement fixes, more)

3

### Main Goals of this pr are now: - [x] update to BinningAnalysis 0.6 (closes #130 and #166) - [x] fix time integrals for susceptibilities - [x] rework the lattice...

This pull request changes the compat entry for the `BinningAnalysis` package from `0.4` to `0.4, 0.6`. This keeps the compat entries for earlier versions. Note: I have not tested your...

See for example Appendix B in http://www.thp.uni-koeln.de/trebst/pubs/HierarchyEnergyScalesAFMQCP.pdf or https://journals.aps.org/prb/abstract/10.1103/PhysRevB.65.115104 Not sure if this should be using the number of unit cells (L^2) or the number of sites (N) yet.

Average sign in DQMC

3

Hi Carsten, Thank you for this wonderful code! Could I ask a quick question regarding the average sign? I am trying the Hubbard model with repulsive U. Can I obtain...

Closes #152 Without reworking stuff there are two options on how to integrate parameter tuning - either via an update or via a measurement. I don't like either option. Both...

Carsten wrote a checkerboard decomposition before I started working with this code. Since then BlockDiagonal and Complex StructArrays have been introduced, but checkerboard decompositions haven't been touched. It would be...

Maybe there is a better way to do this?

Add matrix type for spin/flavour symmetric matrices

2

I.e. a type for matrices of the form `[A 0; 0 A]`. We have this in both default Hubbard models in the hopping matrix. I think this would be useful...

In simulations that allow tuning of the chemical potential we are often more interested in a certain filling fraction/particle number than a specific value of the chemical potential. It would...
