## SLDAE with $`m/m^\star=1`$ ## SLDAE with $`m/m^\star=1`$
The last term of SLDAE functional (depending on currents $`j`$) introduces a significant cost to the computation process. In many cases, it is sufficient to proceed with the functional that neglects corrections related to the effective mass (actually the effective mass is not known with high precision). The W-SLDA Toolkit provides a variant of the SLDAE functional where the constraint $`\alpha_\lambda = m/m^\star=1`$ is imposed. In order to activate it, you need to use a flag (in `predefines.h`): The last term of the SLDAE functional (depending on currents $`j`$) introduces a significant cost to the computation process.
