Pauli equation for BPS monopoles in moduli space

Undertaking the study of behaviour of a BPS monopole moving in the field of another BPS monopole, in moduli space, Dirac's equation has been solved for energy eigen values and it has been shown that spin momentum of an interacting BPS monopole behaves as extra energy source. Introducing suitable spinors, the Pauli equation for a BPS monopole moving in the field of another BPS monopole has been solved in moduli space and it has been shown that adhoc introduction of spin in the system of two BPS monopoles perceptibly modifies the energy eigen values and eigen functions of bound states of the system.
