Ferromagnetic spin correlations in the two-dimensional Hubbard model
Philipp Werner, Xi Chen, Emanuel Gull
We analyze the dynamical nearest-neighbor and next-nearest-neighbor spin correlations in the 4-site and 8-site dynamical cluster approximation to the two-dimensional Hubbard model.…
Dynamical Charge Susceptibility in the Hubbard Model
Xinyang Dong, Xi Chen, Emanuel Gull
We compute the dynamical charge susceptibility in the two-dimensional Hubbard model within the dynamical cluster approximation. In order to understand the connection between charge…
Magnetic Susceptibility and Simulated Neutron Signal in the 2D Hubbard Model
J. P. F. LeBlanc, Shaozhi Li, Xi Chen +4
We compute dynamic spin susceptibilities in the two-dimensional Hubbard model using the method of Dual Fermions and provide comparison to lattice Monte Carlo and cluster dynamical…
Knight shifts, nuclear spin-relaxation rates, and spin echo decay times in the pseudogap regime of the cuprates: Simulation and relation to experiment
Xi Chen, J. P. F. LeBlanc, Emanuel Gull
We study the temperature and doping evolution of the NMR Knight shift, spin relaxation rate, and spin echo decay time in the pseudogap regime of the two-dimensional Hubbard model f…
