Quantum spin models

Transverse Field Ising Model

This section introduces the basics of quantum many-body physics, including lattice models, spin models, and ground state calculations.

- Special transformations can be done on operator expressions comprised exclusively of spin 1/2 operators.

This page details the specific operators available for spin-½ systems (qubits). These operators implement the general Operator interface described in the Operators concept guide.

In the Heisenberg picture of quantum mechanics, operators evolve in time while states remain fixed.
