Which experiment can differentiate a statistical mixture from a superposition state?

I am in trouble with polarization and entanglement. Let's consider three cases : Case 1) : Statistical mixture of $|Hrangle$ and $|Vrangle$ polarized photons Case 2) : Photons...

Finding constraints on acceleration if two objects' positions are related non-linearly

I'm taking a a first-quarter mechanics class at a university and we're currently covering Newton's laws of motion. The problems themselves are pretty similar to what I did in high...

How do generators of the Lie algebra correspond to gauge fields?

I’m tackling physics recreationally from a pure math perspective. Right now I’m looking at just the outline of gauge theory. The Wikipedia article explains that gauge fields correspond to generators...

Why does low ionospheric conductance result in an increase in electric field?

So Anderson et al proposed a model to explain the production of Sub Auroral Ion Drifts. In the paper they talk about how the decrease in ionospheric...

Analogies between electrostatics and steady state heat equation?

In electrostatics we have $$nabla cdot E = rho/varepsilon$$and using the divergence theorem we get $$int_{partialOmega} E cdot hat{n} dS = int_Omega rho/varepsilon dV.$$ This states that the electric...

Lorentz surfaces, conformal metrics and eigenvalues

From what I understand of Lorentz surfaces (spacetimes of dimension 2), it seems that, according to Kulkarni's theorem, two reasonable enough Lorentz surfaces (I am only interested in...

Does the wavelength of an individual quantum particle affect its chances of quantum tunneling through a barrier?

I've read elsewhere about the energy of a wave or wave packet, and the amplitude of its probability amplitude, affecting its odds of quantum tunneling... But what about the wavelength...

Closed curve through an event in spacetime

I'm studying the book Techniques of Differential Topology in Relativity by Roger Penrose and I'm stuck in an exercise he left to the reader. We say that the spacetime ...

Is the $S$-matrix a scalar operator?

The scattering $S$ operator which is defined to be the operator corresponding to $S$ matrix should be rotational invariance, does this imply $S$ operator is a scalar...
