Heterogeneous-k-core versus Bootstrap Percolation on Complex Networks
G. J. Baxter, S. N. Dorogovtsev, A. V. Goltsev +1
We introduce the heterogeneous--core, which generalizes the -core, and contrast it with bootstrap percolation. Vertices have a threshold which may be different at each…
Coulomb interaction in graphene: Relaxation rates and transport
M. Schuett, P. M. Ostrovsky, I. V. Gornyi +1
We analyze the inelastic electron-electron scattering in undoped graphene within the Keldysh diagrammatic approach. We demonstrate that finite temperature strongly affects the scre…
Color-dependent conductance of graphene with adatoms
J. Schelter, P. M. Ostrovsky, I. V. Gornyi +2
We study ballistic transport properties of graphene with a low concentration of vacancies or adatoms. The conductance of graphene doped to the Dirac point is found to depend on the…
Electron spin decoherence in diluted magnetic quantum wells
P. M. Shmakov, A. P. Dmitriev, V. Yu. Kachorovskii
We study electron spin dynamics in diluted magnetic quantum wells. The electrons are coupled by exchange interaction with randomly distributed magnetic ions polarized by magnetic f…
Two-point phase correlations of a one-dimensional bosonic Josephson junction
Thomas Betz, Stephanie Manz, Robert Bücker +8
We realize a one-dimensional Josephson junction using quantum degenerate Bose gases in a tunable double well potential on an atom chip. Matter wave interferometry gives direct acce…
HD/H2 Molecular Clouds in the Early Universe: The Problem of Primordial Deuterium
S. A. Balashev, A. V. Ivanchik, D. A. Varshalovich
We have detected new HD absorption systems at high redshifts, z_abs=2.626 and z_abs=1.777, identified in the spectra of the quasars J0812+3208 and Q1331+170, respectively. Each of…
