Hubbard model

introduction

• The Hubbard model describes hopping electrons on a lattice
• 1968 Lieb and We
  
  • application of Bethe ansatz
• 1972 Takahasi
  
  • string hypothesis
  • replace the Lieb-Wu equations by simpler ones
  • proceeded to drive a set of non-linear integral equations known as thermodynamic Bethe ansatz equations
• algebraic Bethe ansatz for the Hubbard model

 

 

Lieb-Wu equations

• describing Eigenstates of the Hubbard Hamiltonian
  \(\exp(ik_jL)=\prod_{l=1}^{M}\frac{\lambda_{l}-\sin k_j-i u}{\lambda_{l}-\sin k_j+i u}\), \(j=1,\cdots, N\)
  \(\prod_{j=1}^{N}\frac{\lambda_{l}-\sin k_j-i u}{\lambda_{l}-\sin k_j+i u}=\prod_{m=1,m\neq l}^{M}\frac{\lambda_{l}-\lambda_{m}-2i u}{\lambda_{l}-\lambda_{m}+2i u}\), \(l=1,\cdots, M\)
