New paper by Majumdar & Schehr ( who discovered the E^-N^2 vs E^-N asymmetric tails to the Tracy-Widom Distribution in the OP ) looking for phase transitions in random walks.

there already exist methods to generate skewed distributions that are very similar to the ones shown in the article. not sure how this is new. Skewed distributions arise form a more general case of the normal distribution but with added parameters or the use of special functions

The main point is not about generating skewed distributions, it's about "universality" - the same distribution starts popping up in seemingly unrelated settings. E.g., (large) eigenvalues of random matrices is connected to the length of the longest increasing subsequence of permutations. In a sense it's the discovery of a new kind of central limit theorem.

As someone who has studied statistics in college, there is little original or novel about these finding. Any distribution can be reversed-engineered to find its characteristic function.

I find it to be a very approachable paper.

Doesn't this statement apply the any function with a maximum?
