fockit - Quantum many-body operators and solvers
Copyright (C) 2026 H. L. Nourse
What is fockit?
Build many-body models, write your own operator algebras, and test algorithms on them. Quick and simple.
Comes with fermions, bosons and Pauli operators, and you can add your own. Simple exact solvers check your ideas on small systems.
Where to start?
The tests are examples:
tests/test_integration.pyfor the operator algebra.tests/solve/for matrices and solvers.tests/solve/test_symmetries.pyfor symmetry sectors (momentum, reflection, spin flip, spin inversion, particle-hole, point groups).
