On the two-magnon bound states for the quantum Heisenberg chain with variable range exchange
J. Dittrich, V. I. Inozemtsev
The spectrum of finite-difference two-magnon operator is investigated for quantum S=1/2 chain with variable range exchange of the form . It is found…
Electron conduction within Landau level tails of medium-mobility GaAs / AlGaAs heterostructures
P. Svoboda, G. Nachtwei, C. Breitlow +2
The temperature dependence of both components of the resistivity tensor and has been studied at T 4.2 K within IQHE plateaux around filli…
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…
Generalized gradient expansions in quantum transport equations
Petr Král
Gradient expansions in quantum transport equations of a Kadanoff-Baym form have been reexamined. We have realized that in a consistent approach the expansion should be performed al…
A Dedicated Computer for Ising-like Spin Glass Models
J. Pech, A. Tarancon, C. L. Ullod
We present a parallel machine, based on programmable devices, dedicated to simulate spin glass models with Z2 variables and short range interaction. A working prototype is describe…
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…
