PRs from #283 to #334

Changes since v1.1.0

Fixes

• Fixed some rare band artifacts (Reduce min_squared_overlap in bands below 0.5 #284)
• Fixed bug in reverse (Ensure reverse! flips harmonics #285)
• Various plot fixes and updates (Add qplot(::OpenHamiltonian) #273, Bump Makie compat #288, Upgrade to Makie 0.21 #290)
• Remove unnecessary intermediary copies (Avoid extra copy in spectrum #292, Remove unnecessary calls to minimal_callsafe_copy #333)
• Fixed bug in supercell with mincoordination (supercell: build lattice after applying mincoordination #296)
• Fixed bugs in combine (Bug fixes in parametric and/or multiorbital combine #305, Apply ranges to lattices before combine #313)
• Fixed bug when computing the adjoint of parametric models (Bugfix: adjoint of parametric models #312)
• Fixed aliasing bugs (Bugfix: ensure full dealiasing of lattices in attach #319, Bugfix: ensure correct dealiasing of lattices in attach #321)
• Fixed subtle bug due to type-piracy (Remove unintended nameof type piracy #328)

New features

• Unexported Quantica.retarded_eigvals and Quantica.decay_lengths functions for 1D AbstractHamiltonians (Add Quantica.retarded_eigvals and Quantica.decay_lengths (unexported) for leads without contacts #289)
• Unexported Quantica.gap and Quantica.gaps for 1D AbstractHamiltonians (Add experimental Quantica.gap(h::Hamiltonian, µ = 0) convenience function for 1D Hamiltonians #294, More general Quantica.gaps #324)
• We can now use a fast solver used on the Generalized Schur algorithm and adaptive numerical integration to compute the density matrix in 1D and 2D systems (add DensityMatrixSchurSolver #291, GreenSolvers.Schur for 2-dimensional systems #332)
• Serializers/Deserializers for AbstractHamiltonians and OrbitalSliceArrays (Serializers #299, Serializer/AppliedSerializer refactor #301, Relink serializers upon ParametricHamiltonian copy #302)
• Made josephson computation more flexible (Add Quantica.integrand for josephson currents #306, Add custom integration paths and callbacks to josephson and densitymatrix #307, Integration path override in densitymatrix and josephson #309, Fix bug in #309 #310)
• Made densitymatrix computations more powerful (Implement diagonal indexing in available densitymatrix solvers #311)
• Generalized integration paths for josephson and densitymatrix. New Paths submodule (Taking integration paths seriously #325, Disallow integrand params to be different from integration path params #330)
• New meanfield: efficient and general Hartree-Fock-Bogoliubov mean fields (General Hartree-Fock mean fields #316, Symmetry enforcement in meanfield #323, Add selector_hartree and selector_fock to meanfield #326)
• Introduced sitepairs as a more general sparse indexer for GreenFunctions, a kind of "hopping" complement to diagonal (GreenFunction indexing refactor #315)

Refactors

• Did a major rewrite of the indexing machinery for GreenFunctions, to allow for new features, such as general sparse indexing (GreenFunction indexing refactor #315)

Breaking changes

• Converted EigenSolvers into extensions. The relevant libraries have to be imported before the corresponding solvers can be used (EigenSolvers as extensions #298)
• Renamed torus to stitch, and introduced a parametric @stitch (Parametric @torus #331, Breaking: rename torus/@torus to stitch/@stitch #334)
