Scattering approach to Anderson localisation
A. Ossipov
We develop a novel approach to the Anderson localisation problem in a -dimensional disordered sample of dimension . Attaching a perfect lead with the cross-sect…
Entanglement entropy in Fermi gases and Anderson's orthogonality catastrophe
A. Ossipov
We study the ground-state entanglement entropy of a subsystem of size of non-interacting fermions scattered by a potential of finite range . We derive a general relation bet…
Criticality without self-similarity: a 2D system with random long-range hopping
A. Ossipov, I. Rushkin, E. Cuevas
We consider a simple model of quantum disorder in two dimensions, characterized by a long-range site-to-site hopping. The system undergoes a metal-insulator transition -- its eigen…
Dynamical scaling for critical states: is Chalker's ansatz valid for strong fractality?
V. E. Kravtsov, A. Ossipov, O. M. Yevtushenko +1
The dynamical scaling for statistics of critical multifractal eigenstates proposed by Chalker is analytically verified for the critical random matrix ensemble in the limit of stron…
