Non-ergodic delocalized phase in Anderson model on Bethe lattice and regular graph
V. E. Kravtsov, B. L. Altshuler, L. B. Ioffe
We develop a novel analytical approach to the problem of single particle localization in infinite dimensional spaces such as Bethe lattice and random regular graphs. The key ingred…
Multifractal metal in a disordered Josephson Junction Array
M. Pino, V. E. Kravtsov, B. L. Altshuler +1
We report the results of the numerical study of the non-dissipative quantum Josephson junction chain with the focus on the statistics of many-body wave functions and local energy s…
Multifractal states in self-consistent theory of localization: analytical solution
B. L. Altshuler, L. B. Ioffe, V. E. Kravtsov
We consider disordered tight-binding models which Green's functions obey the self-consistent cavity equations . Based on these equations and the replica representation, we derive a…
Non-ergodic phases in strongly disordered random regular graphs
B. L. Altshuler, E. Cuevas, L. B. Ioffe +1
We combine numerical diagonalization with a semi-analytical calculations to prove the existence of the intermediate non-ergodic but delocalized phase in the Anderson model on disor…
Giant magnetoresistance in the variable range hopping regime
L. B. Ioffe, B. Z. Spivak
We predict the universal power law dependence of localization length on magnetic field in the strongly localized regime. This effect is due to the orbital quantum interference. Phy…
Quantum Glass Transition in a Periodic Long-Range Josephson Array
D. M. Kagan, L. B. Ioffe, M. V. Feigel'man
We show that the ground state of the periodic long range Josephson array frustrated by magnetic field is a glass for a sufficiently large Josephson energies despite the absence of…
