The '''Ross melting rule''' states (Eq. 4 <ref>[http://dx.doi.org/10.1103/PhysRev.184.233 Marvin Ross "Generalized Lindemann Melting Law", Physical Review '''184''' pp. 233-242 (1969)]</ref>):

:<math>A = \frac{1}{2} NE(0) - Nk_BT \ln \upsilon  - Nk_BT \ln \upsilon_f^*</math>

where <math>A</math> is the [[Helmholtz energy function]], <math>N</math> is the number of cells, <math>E(0)</math> is the potential at the centre of the cell, 
<math>k_B</math> is the [[Boltzmann constant]], <math>T</math> is the [[temperature]], <math>\upsilon</math> is the volume of the cell, and <math>\upsilon_f^*</math> is the dimensionless reduced volume in configuration space.
===Khrapak melting criteria===
The Khrapak one-phase melting criteria for two dimensional crystals with soft long-ranged interactions is given by (Eq 3 in <ref>[https://doi.org/10.1063/1.5027201 Sergey Khrapak "Note: Melting criterion for soft particle systems in two dimensions", Journal of Chemical Physics 148, 146101 (2018)]</ref>):

:<math>\frac{C_T}{v_T}\approx 4.3</math>

where <math>C_T</math> is the transverse [[Speed of sound | sound velocity]], and  <math>v_T</math> is the [[Maxwell speed distribution | thermal velocity]].
