Thouless time analysis of Anderson and many-body localization transitions

P Sierant, D Delande, J Zakrzewski - Physical Review Letters, 2020 - APS
Spectral statistics of disordered systems encode Thouless and Heisenberg timescales,
whose ratio determines whether the system is chaotic or localized. We show that the scaling …

Universal behavior beyond multifractality of wave functions at measurement-induced phase transitions

P Sierant, X Turkeshi - Physical Review Letters, 2022 - APS
We investigate the structure of many-body wave functions of 1D quantum circuits with local
measurements employing the participation entropies. The leading term in system size …

Localization of Dirac fermions in finite-temperature gauge theory

M Giordano, TG Kovács - Universe, 2021 - mdpi.com
It is by now well established that Dirac fermions coupled to non-Abelian gauge theories can
undergo an Anderson-type localization transition. This transition affects eigenmodes in the …

Measuring nonstabilizerness via multifractal flatness

X Turkeshi, M Schirò, P Sierant - Physical Review A, 2023 - APS
Universal quantum computing requires nonstabilizer (magic) quantum states. Quantifying
the nonstabilizerness and relating it to other quantum resources is vital for characterizing the …

Multifractal finite-size scaling and universality at the Anderson transition

A Rodriguez, LJ Vasquez, K Slevin, RA Römer - Physical Review B …, 2011 - APS
We describe a new multifractal finite-size scaling (MFSS) procedure and its application to
the Anderson localization-delocalization transition. MFSS permits the simultaneous …

Anderson localization and ergodicity on random regular graphs

KS Tikhonov, AD Mirlin, MA Skvortsov - Physical Review B, 2016 - APS
A numerical study of Anderson transition on random regular graphs (RRGs) with diagonal
disorder is performed. The problem can be described as a tight-binding model on a lattice …

Universality in Anderson localization on random graphs with varying connectivity

P Sierant, M Lewenstein, A Scardicchio - SciPost Physics, 2023 - scipost.org
We perform a thorough and complete analysis of the Anderson localization transition on
several models of random graphs with regular and random connectivity. The unprecedented …

Critical exponent for the Anderson transition in the three-dimensional orthogonal universality class

K Slevin, T Ohtsuki - New Journal of Physics, 2014 - iopscience.iop.org
We report a careful finite size scaling study of the metal–insulator transition in Anderson's
model of localization. We focus on the estimation of the critical exponent ν that describes the …

Fractality of wave functions on a Cayley tree: Difference between tree and locally treelike graph without boundary

KS Tikhonov, AD Mirlin - Physical Review B, 2016 - APS
We investigate analytically and numerically eigenfunction statistics in a disordered system
on a finite Bethe lattice (Cayley tree). We show that the wave-function amplitude at the root …

Experimental observation of two-dimensional Anderson localization with the atomic kicked rotor

I Manai, JF Clément, R Chicireanu, C Hainaut… - Physical review …, 2015 - APS
Dimension 2 is expected to be the lower critical dimension for Anderson localization in a
time-reversal-invariant disordered quantum system. Using an atomic quasiperiodic kicked …
