#include <triqs/atom_diag/functions.hpp>

Synopsis

template<bool Complex>

typename atom_diag<Complex>::full_hilbert_space_state_t act (typename atom_diag<Complex>::many_body_op_t const & op,

typename atom_diag<Complex>::full_hilbert_space_state_t const & st,

atom_diag<Complex> const & atom)

Act with operator op on state st

Parameters

• op Operator to act on the state.
• st Initial state vector in the full Hilbert space, written in the eigenbasis of the Hamiltonian.
• atom Solved diagonalization problem.

Returns

Final state vector in the full Hilbert space.
