Magnetic interactions and the pressure phase-diagram of CuGeO3
P. H. M. van Loosdrecht, J. Zeman, G. Martinez +3
A pressure and temperature dependent Raman study of the vibrational and spin dynamics in CuGeO3 is presented. A new low temperature, high pressure phase has been identified, and a…
Two-component plasma in a gravitational field
Gabriel Tellez
In this paper we study a model for the sedimentation equilibrium of a charged colloidal suspension: the two-dimensional two-component plasma in a gravitational field which is exact…
Quantum Diffusion and Tunneling with Parametric Banded Random Matrix Hamiltonians
A. Bulgac, G. Do Dang, D. Kusnezov
The microscopic origin of dissipation of a driven quantum many body system is addressed in the framework of a parametric banded random matrix approach. We find noticeable violation…
A new interpretation of the proton-neutron bound state. The calculation of the binding energy
N. B. Mandache
We treat the old problem of the proton-neutron bound state (the deuteron). Using a new concept of incomplete (partial) annihilation process we derive a formula for the binding ener…
Frustrated Blume-Emery-Griffiths model
G. R. Schreiber
A generalised integer S Ising spin glass model is analysed using the replica formalism. The bilinear couplings are assumed to have a Gaussian distribution with ferromagnetic mean <…
Universal fluctuations in the support of the random walk
F. van Wijland, H. J. Hilhorst
A random walk starts from the origin of a d-dimensional lattice. The occupation number n(x,t) equals unity if after t steps site x has been visited by the walk, and zero otherwise.…
Determination of the Longitudinal Proton Structure Function F_L(x,Q^2) at Low x
C. Adloff
A measurement of the inclusive cross section for the deep-inelastic scattering of positrons off protons at HERA is presented at momentum transfers and…
Critical Properties of gapped spin-1/2 chains and ladders in a magnetic field
R. Chitra, T. Giamarchi
An interesting feature of spin-1/2 chains with a gap is that they undergo a commensurate-incommensurate transition in the presence of an external magnetic field . The system is…
Angular position of nodes in the superconducting gap of YBCO
H. Aubin, K. Behnia, M. Ribault +2
The thermal conductivity of a YBCO single crystal has been studied as a function of the relative orientation of the crystal axes and a magnetic field rotating in the Cu-O planes. M…
Level Curvatures and Conductances: A Numerical Study of the Thouless Relation
D. Braun, E. Hofstetter, G. Montambaux +1
The Thouless conjecture states that the average conductance of a disordered metallic sample in the diffusive regime can be related to the sensitivity of the sample's spectrum to a…
Phenomenology of supersymmetric models with a singlet
U. Ellwanger, M. Rausch de Traubenberg, C. A. Savoy
The supersymmetric extension of the standard model with an additional gauge singlet is analysed in detail in the light of the recent experimental bounds on supersymmetric particles…
Scale Influence on the Energy Dependence of Photon-Proton Cross Sections
S. Aid
The scale dependence of the evolution of photoproduction cross sections with the photon-proton centre of mass energy W is studied using low Q^2 < 0.01 GeV^2 e^+p interactions colle…
Density Waves in a Transverse Electric Field
Gilles Montambaux
In a quasi-one-dimensional conductor with an open Fermi surface, a Charge or a Spin Density Wave phase can be destroyed by an electric field perpendicular to the direction of high…
Quasi-degenerate neutrinos from an abelian family symmetry
P. Binetruy, S. Lavignac, S. Petcov +1
We show that models with an abelian family symmetry which accounts for the observed hierarchies of masses and mixings in the quark sector may also accomodate quasi-degeneracies in…
Leptonic Photons and Nucleosynthesis
J. A. Grifols, E. Masso
Should long-range forces be associated to electron, muon and/or tau quantum number then their ''fine structure constants" are seen to be bound by nucleosynthesis data to be…
Temperature and magnetic field dependence of the lattice constant in spin-Peierls cuprate CuGeO_3 studied by capacitance dilatometry in fields up to 16 Tesla
T. Lorenz, U. Ammerahl, T. Auweiler +3
We present high resolution measurements of the thermal expansion coefficient and the magnetostriction along the a-axis of CuGeO_3 in magnetic fields up to 16 Tesla. From the pronou…
Thermodynamic Properties of the Incommensurate Phase of CuGeO_3
T. Lorenz, U. Ammerahl, R. Ziemes +3
We present high resolution measurements of the specific heat and the thermal expansion of the inorganic spin--Peierls cuprate CuGeO_3 in a magnetic field of 16 Tesla. At the transi…
Measurement of Charged Particle Transverse Momentum Spectra in Deep Inelastic Scattering
C. Adloff, H1 Collaboration
Transverse momentum spectra of charged particles produced in deep inelastic scattering are measured as a function of the kinematic variables x_B and Q2 using the H1 detector at the…
Magneto-polarisability of mesoscopic rings
Yves Noat, Bertrand Reulet, Helene Bouchiat
We calculate the average polarisability of two dimensional mesoscopic rings in the presence of an Aharonov-Bohm flux. The screening is taken into account self-consistently within a…
Exact and asymtotic formulas for overdamped Brownian dynamics
P. J. Forrester, B. Jancovici
Exact and asymptotic formulas relating to dynamical correlations for overdamped Brownian motion are obtained. These formulas include a generalization of the -sum rule from the t…
Branched Polymers with Loops
J. Jurkiewicz, A. Krzywicki
We propose a classification of critical behaviours of branched polymers for arbitrary topology. We show that in an appropriately defined double scaling limit the singular part of t…
Neutrino Mass Models with an Abelian Family Symmetry
Stéphane Lavignac
Abelian family symmetries provide a predictive framework for neutrino mass models. In seesaw models based on an abelian family symmetry, the structures of the Dirac and the Majoran…
