There are no abnormal solutions of the BetheSalpeter equation in the static model
Hassen Jallouli, Hagop Sazdjian
The four-point Green's function of static QED, where a fermion and an antifermion are located at fixed space positions, is calculated in covariant gauges. The bound state spectrum…
Scaling and universality in binary fragmenting with inhibition
Robert Botet, Marek Ploszajczak
We investigate a new model of binary fragmentation with inhibition, driven by the white noise. In a broad range of fragmentation probabilities, the power-law spatiotemporal correla…
Phase Diagram for Charge Density Waves in a Magnetic Field
D. Zanchi, A. Bjeliš, G. Montambaux
The influence of an external magnetic field on a quasi one-dimensional system with a charge density wave (CDW) instability is treated within the random phase approximation which in…
The Superconducting Instabilities of the non half-filled Hubbard Model in Two Dimensions
D. Zanchi, H. J. Schulz
The problem of weakly correlated electrons on a square lattice is formulated in terms of one-loop renormalization group. Starting from the action for the entire Brillouin zone (and…
On Curvature in Noncommutative Geometry
M. Dubois-Violette, J. Madore, T. Masson +1
A general definition of a bimodule connection in noncommutative geometry has been recently proposed. For a given algebra this definition is compared with the ordinary definition of…
A Search for Leptoquarks at HERA
H1 Collaboration, S. Aid et al
A search for leptoquarks at HERA was performed in H1 using 1994 data corresponding to an integrated luminosity of about $3 \pb^{-1}$. Single leptoquarks were searched for i…
Moving glass phase of driven lattices
Thierry Giamarchi, Pierre Le Doussal
We study periodic lattices, such as vortex lattices, driven by an external force in a random pinning potential. We show that effects of static disorder persist even at large veloci…
Jets and Energy Flow in Photon-Proton Collisions at HERA
H1-Collaboration, S. Aid et al
Properties of the hadronic final state in photoproduction events with large transverse energy are studied at the electron-proton collider HERA. Distributions of the transverse ener…
Renormalization group approach to Fermi Liquid Theory
N. Dupuis, G. Chitov
We show that the renormalization group (RG) approach to interacting fermions at one-loop order recovers Fermi liquid theory results when the forward scattering zero sound (ZS) and…
On the Spin Gap Phase of Strongly-Correlated Electrons
P. Lederer, Elihu Abrahams
We discuss the possible existence of a spin-gap phase in the low-doping regime of strongly-correlated two-dimensional electrons within the gauge field description of the t-J model.…
What is the Thouless Energy for Ballistic Systems?
Alexander Altland, Yuval Gefen, Gilles Montambaux
The Thouless energy, $\Ec$ characterizes numerous quantities associated with sensitivity to boundary conditions in diffusive mesoscopic conductors. What happens to these quantities…
The Ideal Conductor Limit
B. Jancovici, G. Tellez
This paper compares two methods of statistical mechanics used to study a classical Coulomb system S near an ideal conductor C. The first method consists in neglecting the thermal f…
The Aharonov-Casher Theorem and the Axial Anomaly in the Aharonov-Bohm Potential
Alexander Moroz
The spectral properties of the Dirac Hamiltonian in the the Aharonov-Bohm potential are discussed. By using the Krein-Friedel formula, the density of states (DOS) for different sel…
Generalization of the Calogero-Cohn Bound on the Number of Bound States
K. Chadan, R. Kobayashi, A. Martin +1
It is shown that for the Calogero-Cohn type upper bounds on the number of bound states of a negative spherically symmetric potential , in each angular momentum state, that is…
Polaronic optical absorption in electron-doped and hole-doped cuprates
P. Calvani, M. Capizzi, S. Lupi +3
Polaronic features similar to those previously observed in the photoinduced spectra of cuprates have been detected in the reflectivity spectra of chemically doped parent compounds…
Temperature dependence of the response function of hot nuclear matter
Abdellatif Abada, Dominique Vautherin
The description of collective motion in nuclei at finite temperature using the framework of the random phase approximation is discussed. We focus on the special case of the isovect…
The two-fermion vector potential of constraint theory from Feynman diagrams
H. Jallouli, H. Sazdjian
The relativistic fermion-antifermion bound state vector potential of constraint theory is calculated, in perturbation theory, by means of the Lippmann-Schwinger type equation that…
The Recoils of a Dynamical Mirror and the Decoherence of its Fluxes
Parentani Renaud
In order to address the problem of the validity of the "background field approximation", we introduce a dynamical model for a mirror described by a massive quantum field. We then a…
SVD Approach to Data Unfolding
Andreas Hoecker, Vakhtang Kartvelishvili
Distributions measured in high energy physics experiments are usually distorted and/or transformed by various detector effects. A regularization method for unfolding these distribu…
Universality in some classical Coulomb systems of restricted dimension
P. J. Forrester, B. Jancovici, G. Tellez
Coulomb systems in which the particles interact through the -dimensional Coulomb potential but are confined in a flat manifold of dimension are considered. The Coulomb p…
Delta-rho in an SU(2) X U(1) chiral Yukawa model
J. L. Alonso, Ph. Boucaud, A. J. van der Sijs
We report on a simulation in progress of an SU(2) X U(1) fermion-Higgs model with two *non-degenerate* fermion doublets. The Zaragoza proposal for chiral lattice fermions is used;…
Variational theory of elastic manifolds with correlated disorder and localization of interacting quantum particles
Thierry Giamarchi, Pierre Le Doussal
We apply the gaussian variational method (GVM) to study the equilibrium statistical mechanics of the two related systems: (i) classical elastic manifolds, such as flux lattices, in…
