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…
How spin-orbit interaction can cause electronic shot noise
A. Ossipov, J. H. Bardarson, C. W. J. Beenakker +2
The shot noise in the electrical current through a ballistic chaotic quantum dot with N-channel point contacts is suppressed for N --> infinity, because of the transition from stoc…
T-duality in supersymmetric theory of disordered quantum systems
A. Ossipov, V. E. Kravtsov
A new super-symmetric representation for quantum disordered systems is derived. This representation is exact and is dual to that of the nonlinear sigma-model. The new formalism is…
Statistics of delay times in mesoscopic systems as a manifestation of eigenfunction fluctuations
A. Ossipov, Y. V. Fyodorov
We reveal a general explicit relation between the statistics of delay times in one-channel reflection from a mesoscopic sample of any spatial dimension and the statistics of the ei…
A super-Ohmic energy absorption in driven quantum chaotic systems
A. Ossipov, D. M. Basko, V. E. Kravtsov
We consider energy absorption by driven chaotic systems of the symplectic symmetry class. According to our analytical perturbative calculation, at the initial stage of evolution th…
