# The Interface Pinning method for studying solid-liquid transitions

This example demonstrate using a bias potential that can be used to study solid-liquid transitions 

with the interface pinning method. This is done by adding a harmonic potential to the Hamiltonian 

that bias the system towards two-phase configurations. 

In this example we will use the interface pinnig method to study a solid-liquid transition.

This is done by adding a harmonic potential to the Hamiltonian 

that bias the system towards two-phase configurations:

  U_bias = 0.5*K*(Q-a)^2
