Estimation of the charge carrier localization length from Gaussian fluctuations in the magneto-thermopower of La_{0.6}Y_{0.1}Ca_{0.3}MnO_3
S. Sergeenkov, H. Bougrine, M. Ausloos +1
The magneto-thermoelectric power (TEP) of perovskite type manganise oxide is found to exhibit a sharp peak at some temperature …
Dual Quantum Monte Carlo Algorithm for Hardcore Bosons
G. G. Batrouni, H. Mabilat
We derive the exact dual representation of the bosonic Hubbard model which takes the form of conserved current loops. The hardcore limit, which corresponds to the quantum spin-${1\…
Modeling the Stock Market prior to large crashes
Anders Johansen, Didier Sornette
We propose that the minimal requirements for a model of stock market price fluctuations should comprise time asymmetry, robustness with respect to connectivity between agents, ``bo…
Crashes as Critical Points
Anders Johansen, Olivier Ledoit, Didier Sornette
We study a rational expectation model of bubbles and crashes. The model has two components : (1) our key assumption is that a crash may be caused by local self-reinforcing imitatio…
Economic returns of research: the Pareto law and its implications
Didier Sornette, Daniel Zajdenweber
At what level should government or companies support research? This complex multi-faceted question encompasses such qualitative bonus as satisfying natural human curiosity, the que…
A New Construction for Spinor Wave Equations
Samuel De Toro Arias, Christian Vanneste
The construction of discrete scalar wave propagation equations in arbitrary inhomogeneous media was recently achieved by using elementary dynamical processes realizing a discrete c…
An Observational Test of the Critical Earthquake Concept
D. D. Bowman, G. Ouillon, C. G. Sammis +2
We test the concept that seismicity prior to a large earthquake can be understood in terms of the statistical physics of a critical phase transition. In this model, the cumulative…
Evidence of discrete scale invariance in DLA and time-to-failure by canonical averaging
A. Johansen, D. Sornette
Discrete scale invariance, which corresponds to a partial breaking of the scaling symmetry, is reflected in the existence of a hierarchy of characteristic scales l0, c l0, c^2 l0,.…
The sharp peak-flat trough pattern and critical speculation
B. M. Roehner, D. Sornette
We find empirically a characteristic sharp peak-flat trough pattern in a large set of commodity prices. We argue that the sharp peak structure reflects an endogenous inter-market o…
Discrete scale invariance in turbulence?
D. Sornette
Based on theoretical argument and experimental evidence, we conjecture that structure functions of turbulent times series exhibit log-periodic modulations decorating their power la…
Stretched exponential distributions in Nature and Economy: ``Fat tails'' with characteristic scales
Jean Laherrère, D. Sornette
To account quantitatively for many reported ``natural'' fat tail distributions in Nature and Economy, we propose the stretched exponential family as a complement to the often used…
Comparative Study of the Adiabatic Evolution of a Nonlinear Damped Oscillator and an Hamiltonian Generalized Nonlinear Oscillator
O. V. Usatenko, J. -P. Provost, G. Vallee +1
In this paper we study to what extent the canonical equivalence and the identity of the geometric phases of dissipative and conservative linear oscillators, established in a precee…
