Dynamical Mean-Field calculation of kinetic energy for the one-band doped Hubbard Model
ORAL
Abstract
We present a Dynamical Mean-Field calculation of the interaction, doping and temperature dependence of the kinetic energy for the one-band doped Hubbard model. We combine Quantum Monte-Carlo and an improved finite temperature Exact Diagonalization method to obtain results over a wide range of temperatures. The overlapping temperature region for the two methods enables an improved error estimation. The results are compared to recent experimental data.
