Lieb-Liniger delta Bose gas

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

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