I Classic 'Double-Slit' Experiment Using Time Instead of Space

Click For Summary
The discussion centers on the article about recreating the classic double-slit experiment using time instead of space, referencing a specific paper on time diffraction at optical frequencies. Participants express skepticism about the novelty of the findings, suggesting that the excitement may be overstated. While the fast optics involved in the experiment are acknowledged as interesting, doubts remain about whether this truly advances the field of light modulation. Comparisons are made to neutrino oscillation experiments, indicating that similar concepts have been explored previously. Overall, the conversation questions the significance of the new approach in the context of established physics.

TL;DR
Physicists Recreate Classic 'Double-Slit' Experiment Using Time Instead of Space

I think the go-fast optics in the actual paper is a lot of fun and the result is satisfying. I dont know whether this expands the state of the art for modulating light fastly (fastly being a Trumpism).
The rest of the hype is just silly IMHO.

I suspected as much. Thank you.

That's effectively what neutrino oscillation experiments have been doing for decades.

Thread 'Angular Momentum Vector and Its Magnitude'

For the quantum state ##|l,m\rangle= |2,0\rangle## the z-component of angular momentum is zero and ##|L^2|=6 \hbar^2##. According to uncertainty it is impossible to determine the values of ##L_x, L_y, L_z## simultaneously. However, we know that ##L_x## and ## L_y##, like ##L_z##, get the values ##(-2,-1,0,1,2) \hbar##. In other words, for the state ##|2,0\rangle## we have ##\vec{L}=(L_x, L_y,0)## with ##L_x## and ## L_y## one of the values ##(-2,-1,0,1,2) \hbar##. But none of these...
