prototype: virtual int AdAdAA (int , int , int , int , int , double& coefficient )

description:apply a^+_m1 a^+_m2 a_n1 a_n2 operator to a given state (with m1+m2=n1+n2)


input parameters:
index = index of the state on which the operator has to be applied
m1 = first index for creation operator
m2 = second index for creation operator
n1 = first index for annihilation operator
n2 = second index for annihilation operator
coefficient = reference on the double where the multiplicative factor has to be stored


return value: index of the destination state

description:apply a^+_m a_m operator to a given state


input parameters:
index = index of the state on which the operator has to be applied
m = index of the creation and annihilation operator


return value: coefficient obtained when applying a^+_m a_m
