The above discussion teaches us that simplifications can happen at larger distances in terms of an effectively new description of the degrees of freedom described by a Hamiltonian relevant for that scale. The separation of scales happens because of the presence of short range forces or different sizes ...

This anisotropic mechanical system is consistent with the non-relativistic Horava's dispersion relation. Our system corresponds to the Conformal Mechanics for z=2 and is a generalization of this system for ar ...
