... go deeper into the structure and geometry of the phase space of Hamiltonian systems. This we do in order to define key concepts that describe the impact of non-linearity on the structure of the phase space, namely, integrability, its breaking due to perturbations, and the emergence of chaotic behavi ...

... (a) The roller coaster released from A can at most make to C, but not to E. Its PE at A is less than the PE at D. When the car is the bottom its energy is totally KE. CD is the energy barrier which prevents the car making to E. In quantum theory, on the other hand, there is a chance that the car cou ...

The number of steps M for a single iteration is chosen to be much smaller than collision time and large enough in order to fill the grid using a limited number of test particles. Since source terms generated in this way are small ...
