TI LAMBDA
TI_LAMBDA = real
Default: TI_LAMBDA = 0.0
Description: TI_LAMBDA defines the coupling parameter [math]\displaystyle{ \lambda }[/math] used in Thermodynamic integration with harmonic reference. The value of [math]\displaystyle{ \lambda }[/math] must be from the inverval [math]\displaystyle{ \langle 0, 1 \rangle }[/math].
