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…
Gyrotropy and magneto-spatial dispersion effects at intersubband transitions in quantum wells
L. E. Golub
Gyrotropic properties of multiple quantum well structures are studied theoretically. Symmetry analysis is performed yielding the gyrotropy tensor components for structures grown al…
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…
Einstein-Podolsky-Rosen Correlations of Ultracold Atomic Gases
Nir Bar-Gill, Christian Gross, Gershon Kurizki +2
Einstein, Podolsky & Rosen (EPR) pointed out that correlations induced between quantum objects will persist after these objects have ceased to interact. Consequently, their joint c…
Stimulated emission of terahertz radiation by semiconductor microcavities
K. V. Kavokin, M. A. Kaliteevski, R. A. Abram +3
We show that planar semiconductor microcavities in the strong coupling regime can be used as sources of stimulated terahertz (THz) radiation. Emitted THz photons would have a frequ…
Diffusion and criticality in undoped graphene with resonant scatterers
P. M. Ostrovsky, M. Titov, S. Bera +2
A general theory is developed to describe graphene with arbitrary number of isolated impurities. The theory provides a basis for an efficient numerical analysis of the charge trans…
Radiative properties of highly magnetized isolated neutron star surfaces and approximate treatment of absorption features in their spectra
V. Suleimanov, V. V. Hambaryan, A. Y. Potekhin +3
In the X-ray spectra of most X-ray dim isolated neutron stars (XDINSs) absorption features with equivalent widths (EWs) of 50 -- 200 eV are observed. We theoretically investigate d…
Scaling Behavior of Heavy Fermion Metals
V. R. Shaginyan, M. Ya. Amusia, A. Z. Msezane +1
Strongly correlated Fermi systems are fundamental systems in physics that are best studied experimentally, which until very recently have lacked theoretical explanations. This revi…
Full counting statistics in disordered graphene at Dirac point: From ballistics to diffusion
A. Schuessler, P. M. Ostrovsky, I. V. Gornyi +1
The full counting statistics of the charge transport through an undoped graphene sheet in the presence of smooth disorder is studied. At the Dirac point both in clean and diffusive…
Tunneling into a Luttinger liquid revisited
D. N. Aristov, A. P. Dmitriev, I. V. Gornyi +3
We study how electron-electron interactions renormalize tunneling into a Luttinger liquid beyond the lowest order of perturbation in the tunneling amplitude. We find that the conve…
Non-Abelian gauge fields in the gradient expansion: generalized Boltzmann and Eilenberger equations
C. Gorini, P. Schwab, R. Raimondi +1
We present a microscopic derivation of the generalized Boltzmann and Eilenberger equations in the presence of non-Abelian gauges, for the case of a non-relativistic disordered Ferm…
HD molecules at high redshift: The absorption system at z=2.3377 towards Q 1232+082
A. V. Ivanchik, P. Petitjean, S. A. Balashev +4
We present a detailed analysis of the H_2 and HD absorption lines detected in the Damped Lyman-alpha (DLA) system at z_abs=2.3377 towards the quasar Q1232+082. We show that this in…
Atom interferometry with trapped Bose-Einstein condensates: Impact of atom-atom interactions
Julian Grond, Joerg Schmiedmayer, Ulrich Hohenester
Interferometry with ultracold atoms promises the possibility of ultraprecise and ultrasensitive measurements in many fields of physics, and is the basis of our most precise atomic…
