Landau quantization in quantum mechanics is the quantization of the cyclotron orbits of charged particles in magnetic fields. As a result, the charged particles can only occupy orbits with discrete energy values, called Landau levels. Derive equation for the Landau levels by using Bohr model and basic electromagnetic? What is difference between derived equation and derived Landau level derived by quantum mechanics?

In the the Bohr model of the atom, electrons travel in circular orbits around a positively charged nucleus in a manner similar to that of our solar system. The electrostatic force provides the attraction, rather than gravity. Furthermore, the orbits are quantized, meaning that only certain orbit are possible. In the case of the hydrogen atom, the electron orbits a proton. The smallest possible orbital radius of the Bohr atom is 0.0529nm, and is called the Bohr radius. How much...

2. A cyclotron is a device used to accelerate charged particles to high speeds. It consists of two hollow containers -called dees because of their shape facing each other and separated by a small gap. They are immersed in a uniform magnetic field, B, and are attached to a source of alternating voltage. A charged particle is projected from the center of the cyclotron into Dee #1, and the magnetic force causes it to turn in a cirele. When it...

PLEASE HELP WITH THESE THREE QUESTIONS What is the orbital frequency (in Hz) of the electron as it orbits about the nucleus in the n = 100006 state of the Hydrogen atom? You can obtain this from the Bohr Model of the Atom by using the equations for the radius of the orbit and the speed of the electron. Since the orbital frequency is the number of revolutions per second that the electron undergoes as it orbits, you can determine...
