Description: Removes sources and drains from the exchange-correlation B field.
With LSFBXC=T, the sources and drains are removed from the exchange-correlation (XC) B field[1] at each step of the electronic minimization. Thus, any XC potential can be constrained to correspond to a Maxwellian magnetic field at the cost of becoming a potential-only XC functional, since there is no correction applied to the XC energy.
Moore et al. implemented the same feature in a parallel work[2][3] and performed more extensive applications. Whether the two implementations are identical has not been tested, and no publication is associated with the present implementation (by Marie-Therese Huebsch) using LSFBXC.
