v1.0.7

What's Changed

Interface changes

• New MatrixBuilder interface allows to control the way a Hamiltonian is generated.
• UniformMatrixBuilder is a way to create a Hamiltonian that allows to skip a costly sparse call. Works good only under assumption the nonzero elements of the matrix are uniformly distributed over columns.

Other updates

• Improved performance of removedangling!.
• Pretty-printing of a BravaisLattice became more compact due to a shorter way of showing basis vectors.

Bugfixes

• site + Translation(vector) now throws a MethodError instead of a StackOverflowError

Merged pull requests

• Performance upgrades by @aryavorskiy in #19

Full Changelog: v1.0.6...v1.0.7

v1.0.6

What's changed

• Now additional point fluxes are automatically added if the lattice has periodic boundary conditions (see #15); you can revert this behavior by setting auto_pbc_field=false.
• Also you can push! or append! magnetic fluxes to PointFluxes objects — purely for convenience.
• The occupations_type keyword was reworked, and now you can set it directly for the anybody system or for a hubbard model Hamiltonian.
• System(mb) allows you to use any many-body basis.
• FermiHubbardSpinSystem is a new way that allows us to fix the number of up- and down-spins on a lattice.
• Performance of hubbard is seriously increased. Use occupations_type=FermionBitstring for yet another performance gain.

PRs merged

• CompatHelper: bump compat for KrylovKit to 0.9, (keep existing compat) by @github-actions in #14
• Add methods for PointFluxes and adapt magnetic fields to boundaries by @aryavorskiy in #16
• Interaction & occupation types by @aryavorskiy in #17

Full Changelog: v1.0.5...v1.0.6

v1.0.5

• The FieldSum type for gauge fields is not suitable for large numbers of members, so a warning is shown if the length of the sum is too much
• Introducing a new PointFluxes gauge field type. It is an efficient representation of a collection of PointFlux fields (requested in #11)
• LatticeValue broadcasting is more flexible and optimized
• Update combat entries

Full Changelog: v1.0.4...v1.0.5

v1.0.4

• Added JET testing, fixed some bugs, typos and type stability issues
• A small optimization in removedangling! makes the lattice creation process up to 15% faster (for large lattices)

Full Changelog: https://github.com/aryavorskiy/LatticeModels.jl/compare/v1.0.3..v1.0.4

v1.0.3

This small release introduces small tweaks and a new plot recipe for large lattices.

What's Changed

• Fix Readme by @aryavorskiy in #9
• Add 'histogram2d' plot recipe by @aryavorskiy in #10

Full Changelog: v1.0.2...v1.0.3

v1.0.2

Finally all small issues are resolved:

• Slight performance improvements
• TTFX reduced due to PrecompileTools integration
• An enhanced logo in ReadMe

Full Changelog: v1.0.1...v1.0.2

v1.0.1

Changes since v1.0.0
