Numerically exploring the 1D-2D dimensional crossover on spin dynamics in the doped Hubbard model
Numerically exploring the 1D-2D dimensional crossover on spin dynamics in the doped Hubbard model
Using determinant quantum Monte Carlo (DQMC) simulations, we systematically study the doping dependence of the crossover from one to two dimensions and its impact on the magnetic properties of the Hubbard model. A square lattice of chains is used, in which the dimensionality can be tuned by varying the interchain …
