Function Documentation

void QCM::anomalous_operator(const string &name, vector3D<int64_t> &link, complex<double> amplitude, int orb1, int orb2, const string &type)

Defines an anomalous operator on the lattice.

Defines an anomalous (pairing) operator.

Parameters:

• name – name given to the operator

• link – bond vector on which the operator is defined

• amplitude – default amplitude of the operator, that multiplies all matrix elements and its given value

• orb1 – index of the first orbital (from 1 to nband)

• orb2 – index of the second orbital (from 1 to nband)

• type – type of pairing: singlet, dx, dy, dz
