introduction

  • N bosons interacting on a line of length L via the delta function potential
  • one-dimensional Bose gas
  • 1963 Lieb and Liniger solved by Bethe ansatz

 

 

 

Hamiltonian

  • quantum mechanical Hamiltonian
    \(H=-\sum_{j=1}^{N}\frac{\partial^2}{\partial x_j^2}+2c\sum_{1\leq i<j\leq N}^{N}\delta(x_i-x_j)\)

 

 

 

two-body scattering term

  • \(s_{ab}=k_a-k_b+ic\)

 

 

Bethe-ansatz equation

\(\exp(ik_jL)=\prod_{l=1}^{N}\frac{k_j-k_l+ic}{k_j-k_l-ic}\)

 

 

energy spectrum

\(E=\sum_{j=1}^{N}k_j^2\)
