Further examples
In this section we present more elaborated examples to illustrate other features of the EDIpack2.0 library.
Specifically, we shall present three examples one for each value of
the ed_mode
variable selecting the type of symmetry,
i.e. quantum number conservation, available in the code.
These examples can be used as a starting point to develop other
problem specific driver.
In the first section we discuss the solution of the interacting BHZ model without additional symmetry breaking as a non-trivial example of multi-orbital problem. Next, we consider the solution of the attractive Hubbard model as a simple description of s-wave superconductivity. Finally, we consider the description of in-plane triplet exciton condensation in the interacting BHZ model to illustrate the use of EDIpack2.0 in cases where spin-SU(2) symmetry is not present.
