The method of image charges (also known as the method of images and method of mirror charges) is a basic problem-solving tool in electrostatics.The name originates from the replacement of certain elements in the original layout with fictitious charges, which replicates the boundary conditions of the problem (see Dirichlet boundary conditions or Neumann boundary conditions).
Mulliken charges arise from the Mulliken population analysis [1] [2] and provide a means of estimating partial atomic charges from calculations carried out by the methods of computational chemistry, particularly those based on the linear combination of atomic orbitals molecular orbital method, and are routinely used as variables in linear regression (QSAR [3]) procedures.

In a unitarity gauge one can set + = and make real. Then ϕ 0 = v {\displaystyle \langle \phi ^{0}\rangle =v} is the non-vanishing vacuum expectation value of the Higgs field. v {\displaystyle v} has units of mass, and it is the only parameter in the Standard Model that is not dimensionless.
i.e., crystallization takes a time that decreases as one over the one-quarter power of the nucleation rate per unit volume, ˙, and one over the three-quarters power of the growth velocity ˙. Typical crystallites grow for some fraction of the crystallization time t X {\displaystyle t_{X}} and so have a linear dimension G ˙ t X {\displaystyle ...

Crystallization is the process by which solids form, where the atoms or molecules are highly organized into a structure known as a crystal.Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
