Dynamical delocalization in disordered 2D Chern insulators
Gianluca Panati, Constanza Rojas-Molina, Vincenzo Rossi
We show the existence of energies exhibiting dynamical delocalization in discrete 2D Chern insulators perturbed by a random potential in a general setting. Our proof exploits two m…
Phase transition in the Integrated Density of States of the Anderson model arising from a supersymmetric sigma model
Margherita Disertori, Valentin Rapenne, Constanza Rojas-Molina +1
We study the Integrated Density of States (IDS) of the random Schrödinger operator appearing in the study of certain reinforced random processes in connection with a supersymmetri…
Decay of the Green's function of the fractional Anderson model and connection to long-range SAW
Margherita Disertori, Roberto Maturana Escobar, Constanza Rojas-Molina
We prove a connection between the Green's function of the fractional Anderson model and the two point function of a self-avoiding random walk with long range jumps, adapting a stra…
