... Physicists were both mystified and intrigued by Bohr’s theory. They questioned why the energies of hydrogen electron are quantized, or, why is the electron in a Bohr atom restricted or orbiting the nucleus at certain fixed distance? For a decade there is no logical explanation. In 1924, Louis de Bro ...

Some Families of Probability Distributions Within Quantum Theory
... Some basics of quantum theory are presented including the way an experiment is modeled. Then states, observables, expected values, spectral measure, and probabilities are introduced. An example of spin measurement is discussed in the context of Stern Gerlach experiments. In order to describe an exam ...

7.2.4. Normal Ordering
... 7.2.4. Normal Ordering In the last section, we get rid of an infinite vacuum energy on the ground that only relative energies have physical meaning. However, if the structure of spacetime is to be determined by matter distribution, the vacuum must be at zero energy. Therefore, we must impose some ru ...

Canonical Quantization
... One of the most direct ways to quantize a classical system is the method of canonical quantization introduced by Dirac. The prescription is remarkably simple, and stems from the close relationship between Hamiltonian mechanics and quantum mechanics. A dynamical variable is any function of the phase ...

SCHRÖDINGER EQUATION FOR A PARTICLE ON A CURVED SPACE AND SUPERINTEGRABILITY
... Abstract. A formulation of quantum mechanics on spaces of constant curvature is studied by quantizing the Noether momenta and using these to form the quantum Hamiltonian. This approach gives the opportunity of studying a superintegrable quantum system. It is shown there are three different ways of o ...

Usually, in classical mechanics, there is a transformation that relates these two approaches. However, for a reparametrizationinvariant systems there are problems when changing from the Lagra ...
