Dynamical properties of quantum many-body systems with long-range interactions
Employing large-scale quantum Monte Carlo simulations, we systematically compute the energy spectra of the two-dimensional (2D) spin-1/2 Heisenberg model with long-range interactions. With the 1/r^{α} ferromagnetic and staggered antiferromagnetic interactions, we find the explicit range in α for the...
