Many-body techniques
4This page details the specific operators available for Fermionic systems. These operators implement the general Operator interface described in the Operators concept guide.
General Operator Transformations- Operator transformations manipulate quantum expressions symbolically.
OperatorsOperators are a central tool for expressing and solving quantum many-body physics problems in Aleph. They underpin Aleph's ability to mix symbolic computation with numerical methods. Operators simplify the expression of quantum objects while avoiding costly memory allocations. This guide reviews the general operator framework.
Spin-½ Operator Transformations- Special transformations can be done on operator expressions comprised exclusively of spin 1/2 operators.
