Detailed Description

Iterates through c^dagger_n1 c^dagger_n2 c_m2 c_m1= delta_{n2,m2} c^dagger_n1 c_m1 - c^dagger_n1 c_m2 c^dagger_n2 c_m1 i.e.: if(m2 != n2): - c^dagger_n1 c_m2 c^dagger_n2 c_m1 if(m2 == n2): - c^dagger_n1 (c_m2 c^dagger_n2 - delta_{n2,m2}) c_m1 i.e. if n2 contained in c_m1|psi>: -> +delta_{n2,m2} c^dagger_n1 c_m1 if n2 not contained in c_m1|psi>: 0

or: go back: if(m2==n2): c^dagger_n1 c^dagger_n2 c_n2 c_m1 = : -c^dagger_n2 (delta_{n1,n2}- c_n2 c^dagger_n1 ) c_m1 = -delta_{n1,n2} c^dagger_n2 c_m1 + c^dagger_n2 c_n2 c^dagger_n1 c_m1 = ( c^dagger_n2 c_n2-delta_{n1,n2} ) c^dagger_n1 c_m1
