Continuum description of profile scaling in nanostructure decay
Continuum description profile scaling nanostructure decay
2015/10/16
The relaxation of axisymmetric crystal surfaces with a single facet below the roughening transition is studied via a continuum approach that accounts for step energy g1 and step-step interaction energ...
Continuum approach to self-similarity and scaling in morphological relaxation of a crystal with a facet
Continuum approach self-similarity and scaling morphological relaxation crystal with a facet
2015/10/16
The morphological relaxation of axisymmetric crystal surfaces with a single facet below the roughening transition temperature is studied analytically for diffusion-limited sDLd and attachment-detachme...
Scaling laws for the non-linear coupling constant of a Bose-Einstein condensate at the threshold of delocalization
Scaling laws the non-linear coupling constant Bose-Einstein condensate threshold of delocalization
2012/2/28
We explore the localization of a quasi-one-, quasi-two-, and three-dimensional ultra-cold gas by a finite-range defect along the corresponding 'free'-direction/s. The time-independent non-linear Schro...
Pathlength scaling in graphs with incomplete navigational information
Graph routing, Geometric routing, Navigability
2011/9/1
The graph-navigability problem concerns how one can nd as short paths as possible between a pair of vertices, given an incomplete picture of a graph.We study the navigability of graphs where the vert...
Longitudinal Scaling of Elliptic Flow in Landau Hydrodynamics
Landau Hydrodynamics Longitudinal Scaling of Elliptic Flow
2011/7/21
This study presents generalization of the Landau hydrodynamic solution for multiparticle production applied to non-central relativistic heavy ion collisions.
On critical scaling at the QCD N_f=2 chiral phase transition
chiral phase transition critical scaling at the QCD N_f=2
2011/7/21
We investigate the critical scaling of the quark propagator of N_f=2 QCD close to the chiral phase transition at finite temperature. We argue that it is mandatory to take into account the back-reactio...
Arbitrary-order Hilbert spectral analysis for time series possessing scaling statistics: a comparison study with detrended fluctuation analysis and wavelet leaders
Arbitrary-order Hilbert spectral analysis time series wavelet leaders
2011/8/5
Abstract: In this paper we present an extended version of Hilbert-Huang transform, namely arbitrary-order Hilbert spectral analysis, to characterize the scale-invariant properties of a time series dir...
Scaling and universality in two dimensions: three-body bound states with short-ranged interactions
two dimensions three-body bound states short-ranged interactions Quantum Gases
2011/10/8
Abstract: The momentum space zero-range model is used to investigate universal properties of three interacting particles confined to two dimensions. The pertinent equations are first formulated for a ...
Scaling and intermittency in incoherent α-shear dynamo
Dynamo magnetic fields MHD turbulence
2011/8/17
Abstract: We consider mean-field dynamo models with fluctuating \alpha effect, both with and without shear. The \alpha effect is chosen to be Gaussian white noise with zero mean and given covariance. ...
Imaginary-Scaling versus Indefinite-Metric Quantization of the Pais-Uhlenbeck Oscillator
Higher derivative theories ghosts indefinite metric Pais-Uhlenbeck Oscillator
2011/9/30
Abstract: Using the Pais-Uhlenbeck Oscillator as a toy model, we outline a consistent alternative to the indefinite-metric quantization scheme that does not violate unitarity. We describe the basic ma...
Time scaling with efficient time-propagation techniques for atoms and molecules in pulsed radiation fields
Time scaling atoms and molecules pulsed radiation fields
2011/9/5
We present an ab initio approach to solve the time-dependent Schrodinger equation to treat electron and photon impact multiple ionization of atoms or molecules. It combines the already known time sca...

Financial factor influence on scaling and memory of trading volume in stock market
Financial facto trading volume stock market
2011/9/13
We study the daily trading volume volatility of 17,197 stocks in the U.S. stock markets during the period 1989–2008 and analyze the time return intervals between volume volatilities above a given th...
Scaling Laws in Particle Physics and Astrophysics
Particle Physics and Astrophysics Scaling Laws
2011/8/30
We have presented a new, quantum-mechanical model for the origin of the angular momentum of celestial bodies. Unlike to the previous classical attempts, our approach gives surprisingly accurate numeri...
Applications of Classical Scaling Symmetry
Classical Scaling Symmetry Solar and Stellar Astrophysics Exactly Solvable and Integrable Systems
2011/7/25
Abstract: Any symmetry reduces a second-order differential equation to a first-order equation: variational symmetries of the action (exemplified by central field dynamics) lead to conservation laws, b...
