Abstract

We give a simple proof to derive the optimal flux which minimizes the ground state energy in the one-dimensional Hubbard model, provided the number of particles is even.

Exact solutions for two interacting particles in a one-dimensional ring with a magnetic flux

Qiming Li, J. Callaway

We solve the one-dimensional extended Hubbard model with a magnetic flux analytically for the case of two particles. We find that bound states are ground states only for attractive interactions. We have studied the variation of the ground-state energy as a function of the flux. For the bound state, the period of the oscillation is half of a flux quantum. The dependence of the magnitude of the energy barrier on the size of the ring is discussed in connection with the possible existence of the flux quantization in the thermodynamic limit.

Spin of the ground state and the flux phase problem on the ring

Fumihiko Nakano

As a continuation of our previous work, we derive the optimal flux phase which minimizes the ground state energy in the one-dimensional many-particle systems, when the number of particles is odd in the absence of on-site interaction and external potential. Moreover, we study the relationship between the flux on the ring and the spin of the ground state through which we derive some information on the sum of the lowest eigenvalues of one-particle Hamiltonians.
