$U$ independent eigenstates of Hubbard model
Ming-Yong Ye, Xiu-Min Lin
TL;DR
This paper introduces methods to construct eigenstates of the 2D Hubbard model that are independent of the interaction strength U, addressing a long-standing unresolved problem in condensed matter physics.
Contribution
The paper presents novel techniques for constructing eigenstates of the Hubbard model that do not depend on the on-site interaction parameter U.
Findings
Eigenstates constructed are independent of U.
Methods provide new insights into the Hubbard model.
Potential applications in understanding strongly correlated systems.
Abstract
Two-dimensional Hubbard model is very important in condensed matter physics. However it has not been resolved though it has been proposed for more than 50 years. We give several methods to construct eigenstates of the model that are independent of the on-site interaction strength .
