Two-hole dynamics in spin ladders
Christoph Jurecka, Wolfram Brenig
We present an analytic theory for the energy spectrum of a two-leg spin ladder doped with two holes. Starting from a pseudo-fermion-bond-boson representation of the corresponding $…

Bond operator mean field theory of the half filled Kondo lattice model
Christoph Jurecka, Wolfram Brenig
We present a bond-operator mean field theory for the Kondo lattice model at half filling in two (2D) and three (3D) dimensions. A continuous quantum phase transition from an antife…

Single-hole dynamics in dimerized and frustrated spin-chains
Christoph Jurecka, Wolfram Brenig
We present a unified account for the coupled single-hole- and spin-dynamics in the spin-gap phase of dimerized and frustrated spin-chains and two-leg spin ladders. Based on the str…
