Excitation spectra of the two dimensional Kondo insulator
C. Groeber, R. Eder
We present a Quantum Monte Carlo study of the temperature dependent dynamics of the two-dimensional Kondo insulator. Working at the so-called symmetrical point allows to perform mi…

Hubbard Fermi surface in the doped paramagnetic insulator
C. Groeber, M. G. Zacher, R. Eder
We study the electronic structure of the doped paramagnetic insulator by finite temperature Quantum Monte-Carlo simulations for the 2D Hubbard model. Throughout we use the moderate…

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…
