... of three quantum numbers (nx, nx, nz). While each state of the system is described by a unique set of quantum numbers, there can be more than one state at a particular energy level. Whenever this happens, the level is said to be degenerate. For example, (112), (121), and (211) are three different st ...

... With one slit closed, the image formed is simply a single-slit pattern. We “know” (i.e., we have constrained) which way the particle went. With both slits open, a particle interferes with itself to produce the observed two-slit interference pattern. This amazing interference effect reflects, in a fu ...

... We have already seen how von Neumann, or projective, measurements work. As we have mentioned, these are not the only kind of measurements. The most general kind of measurements are called POVM’s. POVM stands for positive operator valued measure. We will not be talking about the most general kind of ...

... the term ‘electron’ in 1899 and identified electrons with cathode rays. He showed how vibrations of electron give rise to Maxwell’s electromagnetic waves. In 1896, Lorentz jointly with Pieter Zeeman (1865-1943) explained the Zeeman effect whereby atomic spectral lines are split in the presence of ma ...

... (n+ 12 )h in favor of the zero-point energy. Let us clarify the situation. The essential point is, if n in WSQR can take the value zero, it will violate the uncertainty principle. This is true. By putting n = 0, one deliberately assigns the state as a classical state of rest, which is known to defy ...
