Title: Spontaneous ergodicity breaking in invariant matrix models

We reconsider the status of eigenvectors of a random matrix. Traditionally, the requirement of base invariance has lead to the conclusion that invariant models describe extended systems. We show that deviations of the eigenvalue statistics from the Wigner-Dyson universality reflects itself on the eigenvector distribution. In particular, gaps in the eigenvalue density spontaneously break the U(N) symmetry to a smaller one. Models with log-normal weight, such as the Muttalib ensemble and those emerging in Chern-Simons and ABJM theories, break the U(N) in a critical way, resulting into a multi-fractal eigenvector statistics.
These results pave the way to the exploration of localization problems using random matrices via the study of new classes of observables and potentially to novel, interdisciplinary, applications of matrix models.

KPZ timeline-
  • Revolution I: 1986 - 1999
  • Revolution II: 2000 - 2009
  • Renaissance: 2010 - present

KPZ Playbook

Pierre asked me to provide some references to reviews, etc...

As mentioned, there is the-
i) August 2015 special KPZ issue in the Journal of Statistical Physics (triggered, in part, by IAS-Princeton workshop on Nonequilibrium Growth & Random Matrices), edited by Herbert, which contains a KPZ nano-review by Takeuchi & myself (「in a nutshell」, if you will…)- JSP 160, 794 (2015)
emphasizing numerical & experimental aspects, as well as many mathematically-minded papers, esp. the nice summary of Spohn & Quastel-
JSP 160, 965 (2015). See too, contributions of Corwin, Schutz, & Prolhac.

ii) The inaugural review of the post-2010, mathematically-fueled 「KPZ Renaissance
in which we presently live is the work of Kriecherbauer & Krug- J. Phys. A 43, 403001 (2010).
Later- Ivan Corwin, Random Matrices: Theory Appl. 1, 1130001 (2012)

iii) For early, bedrock developments of the 1st KPZ Revolution, see:
THH & Zhang- Phys. Rep. 254, 215 (1994), &
Krug, Adv. Phys. 46, 139 (1997).

title: Random Paths and Optimization Strategies
How the disorder distribution can affect the long time statistics of directed polymers in random media?
Here we show that, in presence of power law tails, polymer's optimization strategy changes from collective to elitist.
