Title:
Delving into the Wigner's surmise
Abstract:
Abstract:
I will start with a little bit of history by posing the problem that confronted Wigner: that of predicting the distribution of spectral lines of the nucleus. After a building some intuition for what this distribution looks like, I'll go through a rigorous proof of the Wigner surmise (the distribution of eigenvalues of a random matrix) for a 2x2 matrix. Through numerical simulations, I will try to convince you that this result works quite well for larger NxN matrices as well. Then, I will compare it to a distribution of spacings between randomly generated points and try to point out some unique features of the distribution of eigenvalues of a random matrix.
Board Notes:
The notes contains derivations of functional forms of the distributions for:
- Spacing between eigenvalues of a 2x2 random matrix.
- Spacing between consecutive i.i.d random variables in a large number of tosses
