The Kondo crossover in shot noise of a single quantum dot with orbital degeneracy
Kondo crossover orbital degeneracy
2010/11/19
We investigate out of equilibrium transport through an orbital Kondo system realized in a single quantum dot, described by the multiorbital impurity Anderson model. Shot noise and current are calculat...
Stationary and dynamical properties of bistable Langevin model under noise-intensity fluctuation
Superstatistics Stochastic volatility Stationary distribution
2010/11/19
In this paper, we study effects of noise-intensity fluctuations on stationary and dynamical prop-erties of a bistable Langevin model, based on concepts of stochastic volatility model and super-statist...
Sensitivity to noise and ergodicity of an assembly line of cellular automata that classifies density
Statistical Mechanics (cond-mat.stat-mech) Disordered Systems and Neural Networks (cond-mat.dis-nn) Cellular Automata and Lattice Gases (nlin.CG)
2010/11/10
We investigate the sensitivity of the composite cellular automaton of H. Fuk\'{s} (Phys. Rev. E 55, R2081 (1997)) to noise and assess the density classification performance of the resulting probabilis...
Noise induced state transitions, intermittency and universality in the noisy Kuramoto-Sivashinksy equation
Noise induced state transitions intermittency universality noisy Kuramoto-Sivashinksy equation
2010/11/18
We analyze the effect of pure additive noise on the long-time dynamics of the noisy Kuramoto-
Sivashinsky (KS) equation in a regime close to the instability onset. We show that when the noise is high...
The efficiency of extracting single atoms or molecules from an ultracold bosonic reservoir is theoretically investigated for a protocol based on lasers, coupling the hyperfine state in which the atoms...

A High Signal-to-Noise Ratio Composite Spectrum of Gamma-ray Burst Afterglows
Galaxies high-redshift gamma rays bursts
2010/11/10
We present a composite spectrum of 60 long duration gamma-ray burst (GRB) afterglows with
redshifts in the range 0.35 < z < 6.7 observed with low resolution optical spectra. The composite spectrum co...
Kernel random matrices have attracted a lot of interest in recent years, from both practical and theoretical standpoints. Most of the theoretical work so far has focused on the case were the data is s...
Development in the Scattering Matrix Theory: From Spin-Orbit-Coupling Affected Shot Noise to Quantum Pumping
Scattering Matrix Theory Spin-Orbit-Coupling Affected Shot Noise Quantum Pumping
2010/11/23
The review chapter starts by a pedagogical introduction to the general concept of the scattering theory: from the fundamental wave-function picture to the second-quantization language, with the aim to...

Scaling of noise correlations one-dimensional lattice hard-core boson systems
2010/11/24
Noise correlations are studied for systems of hard-core bosons in one-dimensional lattices. We use an exact numerical approach based on the Bose-Fermi mapping and properties of Slater determinants.We ...
