Release notes:

Breaking changes

  • Rewrite addIntr! and addObs! and change the interface. For example, consider a hopping term, now the usage becomes
addIntr!(Root, (Fdag, F), (i, j), (true, true), strength; Z = Z)

where (true, true) means both operators are fermionic. Similarly,

addObs!(Tree, (Fdag, F), (i, j), (true, true); Z = Z)

for the calculation of single-particle correlations.

  • Now a multi-site correlation with duplicated site indices can automatically reduce to a shorter term. For example, in the case of $U_1 \times SU_2$ symmetry, the pairing correlation $\langle \Delta_{12}^\dagger \Delta_{23}\rangle$ can be simply calculated via
addObs!(Tree, U1SUFermions.ΔₛdagΔₛ, (1, 2, 2, 3), (true, true, true, true); Z = U1SUFermions.Z)
  • Support adding 3-site terms, e.g. chiral operator $S_i \cdot (S_j \times S_k)$ pinning field, to the Hamiltonian.
