Is there any difference between Hamiltonian operator and E? Or do we describe H as an operation that is performed over (psi) to give us E as a function of (psi)??

A Hamiltonian operator is a mathematical operator used in quantum mechanics to describe the total energy of a quantum system. It takes into account the kinetic and potential energies of the system and is denoted by the symbol H.
The Hamiltonian operator and the energy operator are often used interchangeably, but there is a subtle difference between the two. The Hamiltonian operator represents the total energy of a system, while the energy operator represents the average energy of a system over time.
In quantum mechanics, the Hamiltonian operator is used to calculate the energy of a quantum system and to determine the time evolution of the system. It is a fundamental tool for understanding the behavior of particles at the quantum level.
The Hamiltonian operator is a mathematical operator, while the Hamiltonian function is a mathematical function that describes the total energy of a classical system. In quantum mechanics, the Hamiltonian operator is used to calculate the energy of a quantum system, while in classical mechanics, the Hamiltonian function is used to describe the energy of a classical system.
The Schrödinger equation is a fundamental equation in quantum mechanics that describes the time evolution of a quantum system. The Hamiltonian operator is a key component of the Schrödinger equation, as it represents the total energy of the system and is used to calculate the time evolution of the system.
