Anderson localization on a simplex
A. Ossipov
We derive a field-theoretical representation for the moments of the eigenstates in the generalized Anderson model. The representation is exact and can be used for the Anderson mode…
Virial expansion of the non-linear sigma model in the strong coupling limit
A. Ossipov
We develop a perturbative approach to study the supersymmetric non-linear sigma model characterized by a generic coupling matrix in the strong coupling limit. The method allows us…
Level number variance and spectral compressibility in a critical two-dimensional random matrix model
A. Ossipov, I. Rushkin, E. Cuevas
We study level number variance in a two-dimensional random matrix model characterized by a power-law decay of the matrix elements. The amplitude of the decay is controlled by the p…
Return probability and scaling exponents in the critical random matrix ensemble
V. E. Kravtsov, A. Ossipov, O. M. Yevtushenko
We study an asymptotic behavior of the return probability for the critical random matrix ensemble in the regime of strong multifractality. The return probability is expected to sho…
Extinction of coherent backscattering by a disordered photonic crystal with a Dirac spectrum
R. A. Sepkhanov, A. Ossipov, C. W. J. Beenakker
Photonic crystals with a two-dimensional triangular lattice have a conical singularity in the spectrum. Close to this so-called Dirac point, Maxwell's equations reduce to the Dirac…
Excitation gap of a graphene channel with superconducting boundaries
M. Titov, A. Ossipov, C. W. J. Beenakker
We calculate the density of states of electron-hole excitations in a superconductor/normal-metal/superconductor (SNS) junction in graphene, in the long-junction regime that the sup…
