Abstract:
The dynamical structure factor is an important observable of quantum magnets but due to numerical and theoretical limitations, it remains a challenge to make predictions for Hubbard-like models beyond one dimension. In this work, we study the magnetic excitations of the triangular lattice Hubbard model including next-nearest-neighbor hopping. Starting from the expected 120∘ and stripe magnetic orders, we compute the magnon spectra within a self-consistent random phase approximation. In the strip...     »
