It is the rotating wave approximation really necessary? There is an experimental evidence of this fact?

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

How are iso-frequency contours plotted?

Let's say we have a standard, regular hexagonal honeycomb with a 3-arm primitive unit cell (something like the figure attached; the figure is only representative and not drawn to scale). The...

Is the zero-zero component of the metric tensor equal to 1 for accelerating reference frames?

Consider the case of negligible gravity but there is an accelerating reference frame. Its origin traces out a trajectory, or world line, seen in some inertial reference frame. The Lorentz metric...

Is light quantisation an illusion?

The photo-electric effect does not support quanta in light, since a light particle moving towards a surface cannot cause an electron to move away from the same surface at a right angle. Instead, a...

Is unified field theory Schrödinger's wave equation or its square?

We assume that the Schrödinger wave equation, iℏ(dψ/dt)= Ĥψ. . . . . (1) is incomplete and cannot be considered a unified field theory. on the other hand, its square, d/dt)partial U= D Nabla^2...

COMSOL simulation of transient wave optics propagation is not physical?

Hi guys, I am trying to simulate a 1 ps long plane wave propagating in a dispersive material, with the wave optics transient module. According to the drude-lorentz model, when the frequency of...

It is interesting, I would like if some one could give me some literature of that. Besides of the computational problems, there are some other special implications?. Thanks!
