Disorder Induced Ferromagnetism in Restricted Geometries
E. Eisenberg, R. Berkovits
We study the influence of on-site disorder on the magnetic properties of the ground state of the infinite Hubbard model. We find that for one dimensional systems disorder has n…
The supersymmetric Camassa-Holm equation and geodesic flow on the superconformal group
Chandrashekar Devchand, Jeremy Schiff
We study a family of fermionic extensions of the Camassa-Holm equation. Within this family we identify three interesting classes: (a) equations, which are inherently hamiltonian, d…
The Fundamental Group of a CP^2 Complement of a Branch Curve as an Extension of a Solvable Group by a Symmetric Group
Mina Teicher
The main result in this paper is as follows: Let S be the branch curve (in the projective plan) of a generic projection of a Veronese surface. Then the fundamental group of the com…
Long-term properties of time series generated by a perceptron with various transfer functions
A. Priel, I. Kanter
We study the effect of various transfer functions on the properties of a time series generated by a continuous-valued feed-forward network in which the next input vector is determi…
Fluctuations of addition spectra of independent quantum systems
Yshai Avishai, Dani Berend, Richard Berkovits
Motivated by recent experiments on large quantum dots, we consider the energy spectrum in a system consisting of particles distributed among independent sub-systems, such…
Magnetic irreversibility and relaxation in assembly of ferromagnetic nanoparticles
R. Prozorov, Y. Yeshurun, T. Prozorov +1
Measurements of the magnetic irreversibility line and time-logarithmic decay of the magnetization are described for three samples composed of regular amorphous, acicu…
