Paramagnetic metal-insulator transition in the 2D Hubbard model
C. Groeber, M. G. Zacher, R. Eder
We study the transition from paramagnetic metal to paramagnetic insulator by finite temperature Quantum Monte-Carlo simulations for the 2D Hubbard model at half-filling. Working at…
Dynamical properties of two doped, coupled Hubbard chains
R. M. Noack, M. G. Zacher, H. Endres +1
Using quantum Monte Carlo (QMC) simulations combined with Maximum Entropy analytic continuation as well as analytical methods, we examine the one- and two-particle dynamical proper…
SO(5) Symmetry in t-J and Hubbard Models
W. Hanke, R. Eder, E. Arrigoni +3
Numerical and analytical results are reviewed, which support SO(5) symmetry as a concept unifying superconductivity and antiferromagnetism in the high-temperature superconductors.…
Dynamics of an SO(5) symmetric ladder model
R. Eder, A. Dorneich, M. G. Zacher +2
We discuss properties of an exactly SO(5) symmetric ladder model. In the strong coupling limit we demonstrate how the SO(3)-symmetric description of spin ladders in terms of bond B…
