Altered inertial response of generic degrees of freedom

A method to alter the inertial response of generic degrees of freedom was discussed. The approach was suggested to reduce the mode spreading of a complex system by altering the real dynamics of the system in favor of a more efficient sampling scheme. The resulting dynamics, after introducing a special Hamiltonian in Cartesian coordinates, were found to be well-behaved and nonsingular, producing stable trajectories over long times.
