wave-particle duality and entanglement

By fundamental definition of a entangled system we can say that if we know the quantum state of one subsystem then we can describe the state of another subsystem. A particle possess wave-particle ...

Anyons as particles?

I'm trying to understand the basics of anyons physics. I understand there is neither a Fock space they live in (because Fock is just the space of (anti-)symmetrized tensor product state, see e.g. ...

de Broglie formula inconsistency

I recently stumbled across a small peculiarity I don't understand: According to de Broglie, the frequency of a matterwave can be written as $f=\frac{E}{h}$, and its wavelength as $\lambda = ...

Constructive and destructive interference in De Broglie matter waves

I'm a little confused about matter waves and especially interference. $\lambda = h/p$ The denominator is momentum and is thus reliant on mass. If we assume that the property holds for particles ...

Wave Particle duality because of discrete time?

If time is discrete, such as the Planck's length, would the transition from one frame of time to the next explain why it appears matter changes from a particle to a wave? During that infinitely small ...

Splitting light into colors, mathematical expression (fourier transforms)

I am trying to solve a problem that includes a function of the light hitting a certain area. My question is, how would I change a function $G(x)$ of photons hitting a certain area to include just ...

What is the difference of observing the double slit experiment - once with our eyes and once with a special device?

We perceive the interference image if we not observe the situation near the slit, and just 2 stripes if we do. What is the difference in the observing? Don't we still observe the electrons in both ...

Crystalography - hardest homework problem i have seen so far

The problem statement: We are observing an electron diffraction on a "Ni" crystal. We point the narrow beam of electrons on a crystal which can be rotated so that we are changing the angle ...

What does happen when we rotate crystal while at the same time we shoot a narrow beam of electrons at it

I know that if we shoot narrow beam of electrons at the crystal (we don't change the angle) we will get a diffraction of electrons according to the brag's law. Therefore we get minimums and maximums ...
