Shadow band in the one-dimensional large Hubbard model

Karlo Penc, Karen Hallberg, Frederic Mila +1

We show that the factorized wave-function of Ogata and Shiba can be used to calculate the dependent spectral functions of the one-dimensional, infinite Hubbard model, and o…

On Matrix Product Ground States for Reaction-Diffusion Models

Haye Hinrichsen, Sven Sandow, Ingo Peschel

We discuss a new mechanism leading to a matrix product form for the stationary state of one-dimensional stochastic models. The corresponding algebra is quadratic and involves four…

Magnetic impurity coupled to interacting conduction electrons

Tom Schork

We consider a magnetic impurity which interacts by hybridization with a system of weakly correlated electrons and determine the energy of the ground state by means of an 1/N_f expa…

Tangent Bifurcation of Band Edge Plane Waves, Dynamical Symmetry Breaking and Vibrational Localization

Sergej Flach

We study tangent bifurcation of band edge plane waves in nonlinear Hamiltonian lattices. The lattice is translationally invariant. We argue for the breaking of permutational symmet…

Impurity state in Haldane gap for S=1 Heisenberg antiferromagnetic chain with bond doping

Xiaqun Wang, Steffen Mallwitz

Using a new impurity density matrix renormalization group scheme, we establish a reliable picture of how the low lying energy levels of a Heisenberg antiferromagnetic chain c…

Statistics of pre-localized states in disordered conductors

Vladimir I. Fal'ko, K. Efetov

The distribution function of local amplitudes of single-particle states in disordered conductors is calculated on the basis of the supersymmetric -model approach using a saddle-…
