The schrodinger equation the energy of a physical system is characterized by its hamiltonian h, which is the sum of its kinetic energy t and its potential energy t v. h-t+v the kinetic energy t of the system is defined only by the momentum p of its center of gravity for velocity ) and its mass t: the potential energy v in which the system evolves is only dependent on the position f of the system's center of mass in a conservative (no losses) environment. v(f) s representative of an energy state e of the system. they are solutions of the schrodinger equation the energy o a quantum system can be described by a wavefunction ψ an eigenvalue problem: t this wavefunction ψ t or the system as the correspondence principle between the classical and the quantum use of the hamiltonian transforms the momentum p and the energy e into operators on the wavefunction: pe öy solving the schrodinger equation now means solving the differential equation:
