introduction

  • N bosons interacting on the line $[0,L]$ of length L via the delta function potential
  • one-dimensional Bose gas
  • 1963 Lieb and Liniger solved by Bethe ansatz

 

Hamiltonian

  • quantum mechanical Hamiltonian

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


wave function

  • $\psi(x_1, x_2, \dots, x_j, \dots,x_N)$
  • $\psi(x_1, \dots, x_N) = \sum_P a(P)\exp \left( i \sum_{j=1}^N k_{Pj} x_j\right)$

$$ a(P) = \prod\nolimits_{1\leq i<j \leq N}\left(1+\frac{ic}{k_{Pi} -k_{Pj}}\right) \ . $$


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

  • energy of a Bethe state

\[E=\sum_{j=1}^{N}k_j^2\]
