Universality conjecture for critical one-dimensional random operators

Let EE be distributed according to the arcsine law, UU be uniform on [0,1][0,1], and let Z\mathcal{Z} be a standard two-sided Brownian motion started from 00, independent of EE and UU. Define

ρ(E)=11E2/41E<2,τ(E)=(σρ(E))2,\rho(E)=\frac{1}{\sqrt{1-E^2/4}}\mathbf{1}_{|E|<2},\qquad \tau(E)=(\sigma\rho(E))^2,

and

S(t)=exp(Zt2t4).S(t)=\exp\left(\frac{\mathcal{Z}_t}{\sqrt{2}}-\frac{|t|}{4}\right).

For each operator in the listed settings, consider the corresponding eigenvectors and their high-eigenvalue or small-parameter scaling regime. Universality conjecture. The eigenvectors have a scaling limit described by the limit in Theorem global_evector in the following settings: the critical continuous one-dimensional random Schrödinger operator, the Sineβ_\beta operator as β0\beta\to0, the stochastic Airy operator as β0\beta\to0 for high eigenvalues, and the random Hill operator for high eigenvalues. This is a proposed extension of the discrete critical model's eigenvector limit to several one-dimensional random operators. The cited works indicate related settings, but the supplied text does not establish the conjectured common limit or state its resolution, so the status remains open.
