Spin quantum Hall transition on random networks: exact critical exponents via quantum gravity
Esteban MacÃas, Ilya Gruzberg, Eldad Bettelheim
We solve the problem of the spin quantum Hall transition on random networks using a mapping to classical percolation that focuses on the boundary of percolating clusters. Using too…

A Riemann-Hilbert Approach to Slavnov Overlaps in the Lieb-Liniger model
Eldad Bettelheim
We provide a method to compute Slavnov overlaps in the Lieb-Liniger model using the steepest descent method of the Riemann-Hilbert problem. To do so, we employ the Matsuo-Kostov Re…

Full Statistics of Regularized Local Energy Density in a Freely Expanding Kipnis-Marchioro-Presutti Gas
Eldad Bettelheim, Baruch Meerson
We combine the Macroscopic Fluctuation Theory and the Inverse Scattering Method to determine the full long-time statistics of the energy density averaged over a given spat…
