A duality for Spin Verlinde spaces and Prym theta functions
C. Pauly, S. Ramanan
We prove canonical isomorphisms between Spin Verlinde spaces, i.e, spaces of global sections of a determinant line bundle over the moduli space of semistable Spin-bundles over a sm…
Exact duality and dual Monte-Carlo simulation for the Bosonic Hubbard model
F. Hebert, G. G. Batrouni, H. Mabilat
We derive the exact dual to the Bosonic Hubbard model. The dual variables take the form of conserved current loops (local and global). Previously this has been done only for the ve…
Artifactual log-periodicity in finite size data: Relevance for earthquake aftershocks
Y. Huang, A. Johansen, M. W. Lee +2
The recently proposed discrete scale invariance and its associated log-periodicity are an elaboration of the concept of scale invariance in which the system is scale invariant only…
Fundamental Framework for Technical Analysis
J. V. Andersen, S. Gluzman, D. Sornette
Starting from the characterization of the past time evolution of market prices in terms of two fundamental indicators, price velocity and price acceleration, we construct a general…
Disorder Averaging and Finite Size Scaling
Karim Bernardet, Ferenc Pazmandi, G. G. Batrouni
We propose a new picture of the renormalization group (RG) approach in the presence of disorder, which considers the RG trajectories of each random sample (realization) separately…
Cluster Emission of Be in the Si+C Fusion Reaction at Low Temperature
M. Rousseau, C. Beck, C. Bhattacharya +6
Inclusive as well as exclusive energy spectra of the light charged particles emitted in the Si (=112.6 MeV) + C reaction has been measured using the {\bf ICA…
Phase separation in supersolids
G. G. Batrouni, R. T. Scalettar
We study quantum phase transitions in the ground state of the two dimensional hard-core boson Hubbard Hamiltonian. Recent work on this and related models has suggested ``supersolid…
Self-Organized Percolation Model for Stock Market Fluctuations
Dietrich Stauffer, D. Sornette
In the Cont-Bouchaud model [cond-mat/9712318] of stock markets, percolation clusters act as buying or selling investors and their statistics controls that of the price variations.…
Enriques Surfaces and other Non-Pfaffian Subcanonical Subschemes of Codimension 3
David Eisenbud, Sorin Popescu, Charles Walter
We give examples of subcanonical subvarieties of codimension 3 in projective n-space which are not Pfaffian, i.e. defined by the ideal sheaf of submaximal Pfaffians of an alternati…
Quaternionic Gamma functions and their logarithmic derivatives as spectral functions
Jean-Francois Burnol
We establish Connes's local trace formula (related to the explicit formulae of number theory) for the quaternions. This is done as an application of a study of the central operator…
Financial ``Anti-Bubbles'': Log-Periodicity in Gold and Nikkei collapses
A. Johansen, D. Sornette
We propose that imitation between traders and their herding behaviour not only lead to speculative bubbles with accelerating over-valuations of financial markets possibly followed…
Role of deformation in the decay of Ni and Ca di-nuclei
C. Bhattacharya, M. Rousseau, C. Beck +4
Inclusive as well as exclusive energy spectra of the light charged particles emitted in the reactions have been measured at the Strasb…
Negative magnetoresistance in La(0.6)Y(0.1)Ca(0.3)MnO(3): Evidence for charge localization governed by the Curie-Weiss law
S. Sergeenkov, H. Bougrine, M. Ausloos +1
Colossal negative magnetoresistance Δρ(T,B) observed in La(0.6)Y(0.1)Ca(0.3)MnO(3) at B=1T shows a nearly perfect symmetry around T_0=160K suggesting a universal field-induced tran…
