Witryna22 maj 2015 · Hamiltonian gives the energy of a system. Let's discuss the case of pure states (where we have quantum states that can be written as vectors ). Conservation of energy means that the (expectation value of) amount of energy does not change in time, i.e. . You can write down the time evolution of the expectation value of an operator as: WitrynaFor a system defined by the Hamiltonian , a function f of the generalized coordinates q and generalized momenta p has time evolution and hence is conserved if and only if . Here denotes the Poisson bracket . Lagrangian mechanics [ edit] Suppose a system is defined by the Lagrangian L with generalized coordinates q.
