Magnetic Doublon Bound States in the Kondo Lattice Model
Roman Rausch, Michael Potthoff, Norio Kawakami
We present a novel pairing mechanism for electrons, mediated by magnons. These paired bound states are termed ``magnetic doublons''. Applying numerically exact techniques (full dia…
Phase diagram of the Kondo model on the zigzag ladder
Matthias Peschke, Lena-Marie Woelk, Michael Potthoff
The effect of next-nearest-neighbor hopping on the ground-state phase diagram of the one-dimensional Kondo lattice is studied with density-matrix renormalization-group tech…
Pump-probe Auger-electron spectroscopy of Mott insulators
Roman Rausch, Michael Potthoff
In high-resolution core-valence-valence (CVV) Auger electron spectroscopy from the surface of a solid at thermal equilibrium, the main correlation satellite, visible in the case of…
