**3D-lattice kinetic Monte Carlo coding**

**3D-lattice kinetic Monte Carlo simulation**
atoms and vacancies occupy lattice sites
unary system: atoms ('1') and vacancies ('0')
example: starting evaporation of a spherical cluster in empty space (perspective view)
atomic migration (left) is modeled by shifting 1's in the virtual bit space (right)
conserved-order-parameter Ising model with nearest neighbor (NN) interaction J_{NN}
f.c.c. lattice (12 NNs; J_{NN}/kT_{c} = 0.40837) with periodic boundaries; here: J_{NN}/kT = 1.0
color key: coordination number from red (monomers) to purple (12 NNs)
simulation cell size = (128 × 128 × 128) a^{3} = 1'048'576 lattice sites
number of atoms = 7011
time is measured in Monte Carlo steps (MCS)
