[edit] Ross melting rule

The Ross melting rule states (Eq. 4 ^[4]):

\[A = \frac{1}{2} NE(0) - Nk_BT \ln \upsilon - Nk_BT \ln \upsilon_f^*\]

where \(A\) is the Helmholtz energy function, \(N\) is the number of cells, \(E(0)\) is the potential at the centre of the cell, \(k_B\) is the Boltzmann constant, \(T\) is the temperature, \(\upsilon\) is the volume of the cell, and \(\upsilon_f^*\) is the dimensionless reduced volume in configuration space.
