Breaking changes
Such changes do affect the public interfaces that users interact with.
Fermion/boson/spin/phonon indexes and operators
-
Construction of fermion/boson/spin/phonon indexes and operators are changed.
𝕗(\bbf<tab>ferimion),𝕓(\bbb<tab>, boson),𝕊(\bbS<tab>, spin),𝕦(\bbu<tab>, displacement of lattice vibration) and𝕡(\bbp<tab>, momentum of lattice vibration) are the new interfaces to construct and display such indexes and operators. -
Underlying types to implement fermion/boson/spin/phonon indexes and operators are renamed: 1) the abstract type
IID=>InternalIndex, and the concrete typesFID=>FockIndex,SID=>SpinIndex,PID=>PhononIndex; 2)CompositeIndex=>CoordinatedIndex. -
The
:iidattribute ofIndexnow is renamed to:internal.
Coupling
- A new type,
Pattern, is introduced to represent the coupling pattern in aCoupling. - Construction of
Couplingwith constraints now uses a new macro,@pattern. The old@indexesmacro is removed. Couplingwith different types ofIndexes now must be initialized with the@patternmacro.- The
:siteattribute of anIndexused to construct aCouplingcan no longer be an integer; it must now be either a:or anOrdinalto clearly indicate that it represents the ordinal in a bond.
Quantum numbers
Quantum numbers are completely redesigned.
Mechanism changes
Such changes typically do not affect the public interfaces that users interact with, but they are significant for developers looking to extend this package.
- New function
Patternruleis introduced to implement default rules for coupling patterns. - Interface of
script, which is used to support latex-formatted output of operators, is changed. - Interface of
expandfor aCouplingis changed. - Interfaces of
Toolkit.VectorSpaceare changed.
