triqs::hilbert_space::imperative_operator::operator()

#include <triqs/hilbert_space/imperative_operator.hpp>

Synopsis

template<typename StateType, typename Args>

StateType operator() (StateType const & st, Args &&… args) const

Act on a state and return a new state

The optional extra arguments args… are forwarded to the coefficients of the operator.

auto psi = op(phi,args…);

We apply an operator obtained from op by replacing its monomial coefficients with values returned by coeff(args…). This feature makes sense only for ScalarType being a callable object.

Template parameters

• StateType Type of the initial state
• Args Types of the optional arguments

Parameters

• st Initial state
• args Optional argument pack passed to each coefficient of the operator
