triqs::hilbert_space::make_zero_state

#include <triqs/hilbert_space/state.hpp>

Synopsis

template<typename HilbertSpace, typename ScalarType, bool BasedOnMap>
state<HilbertSpace, ScalarType, BasedOnMap> make_zero_state (state<HilbertSpace, ScalarType, BasedOnMap> const & st)

Make a copy of a given state with all amplitudes set to 0

Template parameters

  • HilbertSpace Hilbert space type, one of [[hilbert_space]] and [[sub_hilbert_space]]

  • ScalarType Amplitude type, normally double or std::complex<double>

  • BasedOnMap Use the implementation based on a map

Parameters

  • st State object to copy
