Coexistence of s-wave Superconductivity and Antiferromagnetism
M. Feldbacher, F. F. Assaad, F. Hebert +1
We study the phase diagram of a new model that exhibits a first order transition between s-wave superconducting and antiferromagnetic phases. The model, a generalized Hubbard model…
Self-similar Approximants of the Permeability in Heterogeneous Porous Media from Moment Equation Expansions
S. Gluzman, D. Sornette
We use a mathematical technique, the self-similar functional renormalization, to construct formulas for the average conductivity that apply for large heterogeneity, based on pertur…
Collective Origin of the Coexistence of Apparent RMT Noise and Factors in Large Sample Correlation Matrices
Y. Malevergne, D. Sornette
Through simple analytical calculations and numerical simulations, we demonstrate the generic existence of a self-organized macroscopic state in any large multivariate system posses…
Foreshocks Explained by Cascades of Triggered Seismicity
Agnes Helmstetter, Didier Sornette
The observation of foreshocks preceding large earthquakes and the suggestion that foreshocks have specific properties that may be used to distinguish them from other earthquakes ha…
Magnon-polaron and Spin-polaron Signatures in the Specific Heat and Electrical Resistivity of in Zero Magnetic Field, and the Effect of Bond Environment
M. Ausloos, L. Hubert, S. Dorbolo +2
, an perovskite manganite oxide, exhibits a non trivial behavior in the vicinity of the sharp peak found in the resistivity as a funct…
Predictability in the ETAS Model of Interacting Triggered Seismicity
A. Helmstetter, D. Sornette
As part of an effort to develop a systematic methodology for earthquake forecasting, we use a simple model of seismicity based on interacting events which may trigger a cascade of…
Roughness of Interfacial Crack Front: Correlated Percolation in the Damage Zone
Jean Schmittbuhl, Alex Hansen, G. George Batrouni
We show that the roughness exponent zeta of an in-plane crack front slowly propagating along a heterogeneous interface embeded in a elastic body, is in full agreement with a correl…
Highly deformed Ca configurations in Si + C
M. Rousseau, C. Beck, C. Bhattacharya +16
The possible occurrence of highly deformed configurations in the Ca di-nuclear system formed in the Si + C reaction is investigated by analyzing the spectra of…
Endogeneous Versus Exogeneous Shocks in Systems with Memory
D. Sornette, A. Helmstetter
Systems with long-range persistence and memory are shown to exhibit different precursory as well as recovery patterns in response to shocks of exogeneous versus endogeneous origins…
Spin and charge dynamics of stripes in doped Mott insulators
F. F. Assaad, V. Rousseau, F. Hebert +2
We study spin and charge dynamics of stripes in doped Mott insulators by considering a two-dimensional Hubbard model with N fermion flavors. For N =2 we recover the normal one-band…
The $-game
Jorgen Vitting Andersen, Didier Sornette
We propose a payoff function extending Minority Games (MG) that captures the competition between agents to make money. In constrast with previous MG, the best strategies are not al…
Symplectic Resolutions for Nilpotent Orbits
Baohua Fu
We prove that any symplectic resolution of the closure of a nilpotent orbit in a semi-simple complex Lie algebra is isomorphic to the collapsing of the cotangent bundle of a projec…
Destruction of diagonal and off-diagonal long range order by disorder in two-dimensional hard core boson systems
K. Bernardet, G. G. Batrouni, M. Troyer +1
We use quantum Monte Carlo simulations to study the effect of disorder, in the form of a disordered chemical potential, on the phase diagram of the hard core bosonic Hubbard model…
Predicting critical crashes? A new restriction for the free variables
Hans-Christian v. Bothmer, Christian Meister
Several authors have noticed the signature of log-periodic oscillations prior to large stock market crashes [cond-mat/9509033, cond-mat/9510036, Vandewalle et al 1998]. Unfortunate…
The Frobenius map, rank 2 vector bundles and Kummer's quartic surface in characteristic 2 and 3
Yves Laszlo, Christian Pauly
Let X be a smooth projective curve of genus g>1 defined over an algebraically closed field k of characteristic p>0. Let M_X(r) be the moduli space of semi-stable rank r vector bund…
Experimental investigation of the robustness of partially entangled photons over 11km
R. T. Thew, S. Tanzilli, W. Tittel +2
We experimentally investigate the robustness of maximal and non-maximal Time-Bin entangled photons over distances up to 11 km. The entanglement is determined by controllable parame…
Mott Domains of Bosons Confined on Optical Lattices
G. G. Batrouni, V. Rousseau, R. T. Scalettar +4
In the absence of a confining potential, the boson Hubbard model in its ground state is known to exhibit a superfluid to Mott insulator quantum phase transition at commensurate fil…
Diffusion of Earthquake Aftershock Epicenters, Omori's Law and Generalized Continuous-Time Random Walk Models
A. Helmstetter, D. Sornette
The epidemic-type aftershock sequence model (ETAS) is a simple stochastic process modeling seismicity, based on the two best-established empirical laws, the Omori law (power law de…
Fractal Plate Tectonics
D. Sornette, V. F. Pisarenko
We analyze in details the statistical significance of the claim by Bird [2002] of a power law distribution of plate areas covering the Earth and confirm that the power law with exp…
Degradation of LaMnO{3-y} surface layer in LaMnO{3-y}/ metal interface
A. Plecenik, K. Frohlich, J. P. Espinos +4
We report electrical measurements showing the degradation processes of LaMnO (LaMnO) in LaMnO/normal metal interface in both point contact and planar-type junctions. Immedi…
