16 and 106, you will enjoy it. It has been downloaded over 300 000 times. It is a physics manual and a physics workbook. But above all, it is a guide to enjoying physics and nature. Because of its close relation to the time-evolution of a system, it is of fundamental importance in most formulations of quantum theory.
The Hamiltonian is the sum of the kinetic energies of all the particles, plus the potential energy of the particles associated with the system. For different situations or number of particles, the Hamiltonian is different since it includes the sum of kinetic energies of the particles, and the potential energy function corresponding to the situation. This is the approach commonly taken in introductory treatments of quantum mechanics, using the formalism of Schrödinger’s wave mechanics. One can also make substitutions to certain variables to fit specific cases, such as some involving electromagnetic fields. Since the potential energy depends on the spatial arrangement of the particles, the kinetic energy will also depend on the spatial configuration to conserve energy. The motion due to any one particle will vary due to the motion of all the other particles in the system.
The potential energy function can only be written as above: a function of all the spatial positions of each particle. Hamiltonian of the system is the sum of the separate Hamiltonians for each particle. This is an idealized situation – in practice the particles are almost always influenced by some potential, and there are many-body interactions. The Hamiltonian generates the time evolution of quantum states. We note again, however, that for common calculations the physicists’ formulation is quite sufficient.
