In fact, the Hamiltonian is often just the total energy in mechanical systems, although this isn’t always the case. Let us for the moment specialize the discussion to planar systems, i.e. systems for which n = 1. The fact that H is constant is means that the motion is constrained to the curve H(x; p) = h, where
A Hamiltonian system is a dynamical system governed by Hamilton's equations. In physics, this dynamical system describes the evolution of a physical system such as a planetary system or an electron in an electromagnetic field. These systems can be studied in both Hamiltonian mechanics and dynamical systems theory.
In quantum mechanics, the Hamiltonian of a system is an operator corresponding to the total energy of that system, including both kinetic energy and potential energy. Its spectrum, the system's energy spectrum or its set of energy eigenvalues, is the set of possible outcomes obtainable from a measurement of the system's total energy.
For a Hamiltonian system, the functions (analogous to the f s in our previous treatment) that give the time dependence of the state space variables can be written as (partial) derivatives of some common function, namely, the Hamiltonian. As we shall see in the next section, that crucial feature embodies the special nature of Hamiltonian systems.
A Hamiltonian system is also known as a canonical system. In the autonomous case, it is referred to as a conservative system, as the function H (which often represents energy) is a first integral, meaning the energy is conserved during motion.
This is a Hamiltonian system with total energy mi i kqi − qjk . Here qi, pi ∈ R3 represent the position and momentum of the ith particle of mass mi, and Vij(r) (i > j) is the interaction potential between the ith and jth particle. The equations of motion read ̇qi = ̇pi = where, for i > j, we have νij = νji = −V ij(rij)/rij ′ with rij = kqi − qjk.

In quantum mechanics, the Hamiltonian of a system is an operator corresponding to the total energy of that system, including both kinetic energy and potential energy. Its spectrum, the system''s energy spectrum or its set of energy eigenvalues, is the set of possible outcomes obtainable from a measurement of the system''s total energy. Due to its close relation to the energy spectrum and time-evolution of a system, it is of fundamental importance in most formulations of quantum theory.
