Wigner crystal versus fermionization for one-dimensional Hubbard models with and without long-range interactions
The ground state properties of Hubbard model with or without long-range interactions in the regime with strongly repulsive on-site interaction are investigated by means of the exact diagonalization method.We show that the appearance of N -crests in the density profile of a trapped N-fermion system is a natural result of …
