    2d Separation
Click For Summary
There is ongoing debate regarding the existence of spin-charge separation in two-dimensional materials, with various studies presenting conflicting results. Some researchers claim to have observed evidence supporting spin-charge separation, while others argue that the findings are inconclusive or misinterpreted. The lack of consensus is partly due to the complexity of experimental setups and the difficulty in isolating spin and charge dynamics. The discussion highlights the need for more rigorous experiments and theoretical frameworks to clarify this phenomenon. Overall, the topic remains an active area of research in condensed matter physics.

TL;DR
I am requesting a simple qualitative basic answer to my question. It is for a presentation for class.
I just want to know if there is a consensus on experimental evidence of spin-charge separation in 2d?

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...
