template<size_t Ns>

void sc::FermionBasicNCOper< 1, FermionOccupationBitString< Ns > >::apply

(

FermionOccupationBitString< Ns > &

os

)

const [inline]

applies this operator to_ FermionOccupationBitString os.

to_==from_ is allowed.

Parameters:

os	the FermionOccupationBitString object

Returns:

FermionOccupationBitString obtained by removing a particle from_ from_ and adding a particle to_ to_.

template<size_t Ns>

bool sc::FermionBasicNCOper< 1, FermionOccupationBitString< Ns > >::apply_sign

(

FermionOccupationBitString< Ns > &

os

)

const [inline]

same as apply(), but returns whether application operator changes the sign of the state; the sign changes if the number of occupied states "crossed" by the operator is odd

Parameters:

os	the FermionOccupationBitString object

Returns:

true is the sign of the state changes

(

const FermionOccupationBitString< Ns > &

os

)

const [inline]

similar to_ apply_sign(), but keeps the argument unchanged

Parameters:

os	the FermionOccupationBitString object

Returns:

new pair[sign_change,FermionOccupationBitString]

template<size_t Ns>
