A meson exchange model for the YN interaction
J. Haidenbauer, W. Melnitchouk, J. Speth
We present a new model for the hyperon-nucleon (Lambda N, Sigma N) interaction, derived within the meson exchange framework. The model incorporates the standard one boson exchange…
Between Poisson and GUE statistics: Role of the Breit-Wigner width
Klaus M. Frahm, Thomas Guhr, Axel M"uller-Groeling
We consider the spectral statistics of the superposition of a random diagonal matrix and a GUE matrix. By means of two alternative superanalytic approaches, the coset method and th…
Spectral correlations in the crossover between GUE and Poisson regularity: on the identification of scales
Thomas Guhr, Axel Mueller-Groeling
Motivated by questions of present interest in nuclear and condensed matter physics we consider the superposition of a diagonal matrix with independent random entries and a GUE. The…
Two interacting particles in a random potential: mapping onto one parameter localization theories without interaction
Klaus Frahm, Axel Mueller-Groeling, Jean-Louis Pichard
We consider two models for a pair of interacting particles in a random potential: (i) two particles with a Hubbard interaction in arbitrary dimensions and (ii) a strongly bound pai…
Conductance length autocorrelation in quasi one-dimensional disordered wires
Klaus Frahm, Axel Mueller-Groeling
Employing techniques recently developed in the context of the Fokker--Planck approach to electron transport in disordered systems we calculate the conductance length correlation fu…
Comment on "No enhancement of the localization length for two interacting particles in a random potential"
Klaus Frahm, Axel Mueller-Groeling, Jean-Louis Pichard +1
In a recent letter [Phys. Rev. Lett. 78, 515 (1997); cond-mat/9612034] Roemer and Schreiber report on numerical calculations that led them to conclude that the previously observed…
Effective Model Formulation for Two Interacting Electrons in a Disordered Metal
Klaus Frahm, Axel M"uller--Groeling, Jean-Louis Pichard
We derive an analytical theory for two interacting electrons in a --dimensional random potential. Our treatment is based on an effective random matrix Hamiltonian. After mapping…
Analytical Results for Random Band Matrices with Preferential Basis
Klaus Frahm, Axel Müller--Groeling
Using the supersymmetry method we analytically calculate the local density of states, the localiztion length, the generalized inverse participation ratios, and the distribution fun…
--Oscillations for Correlated Electron Pairs in Disordered Mesoscopic Rings
D. Weinmann, A. Mueller-Groeling, J. -L. Pichard +1
The full spectrum of two interacting electrons in a disordered mesoscopic one--dimensional ring threaded by a magnetic flux is calculated numerically. For ring sizes far exceeding…
Scaling in Interaction-Assisted Coherent Transport
K. Frahm, A. Mueller-Groeling, J. -L. Pichard +1
The pair localization length of two interacting electrons in one--dimensional disordered systems is studied numerically. Using two direct approaches, we find $L_2 \propto L_1…
Anisotropy and scaling corrections in turbulence
Detlef Lohse, Axel Müller-Groeling
Two parametrizations for second order velocity moments, the Batchelor parametrization for the r-space structure function and a common parametrization for the energy spectrum, $E(p)…
Bottleneck effects in turbulence: Scaling phenomena in r- versus p-space
Detlef Lohse, Axel Mueller-Groeling
We (analytically) calculate the energy spectrum corresponding to various experimental and numerical turbulence data analyzed by Benzi et al.. We find two bottleneck phenomena: Whil…
