Hidden Duality and associated instabilities of Tomonaga-Luttinger Liquid on Lattice
Z. N. C. Ha
Hidden duality and associated instabilities of the spinless Luttinger liquid on lattice are reported. The local quantum fluctuations and the long-distance chiral modes compete and…
New Paired-Wavefunction for the Frustrated Antiferromagnetic Spin-Half Chain
Z. N. C. Ha
I propose a new paired-wavefunction with a parameter that continuously interpolates from the 1D Jastrow-product to the Majumdar-Ghosh dimer-wavefunction appropriate for the frustra…
Fractional Statistics in One-Dimension: View From An Exactly Solvable Model
Z. N. C. Ha
One-dimensional fractional statistics is studied using the Calogero-Sutherland model (CSM) which describes a system of non-relativistic quantum particles interacting with inverse-s…
Elementary Excitations of One-Dimensional t-J Model with Inverse-Square Exchange
Z. N. C. Ha, F. D. M. Haldane
We identify exact excitation content of the intermediate states for the one-particle Green's functions, spin-spin and (charge) density-density correlation functions of the periodic…
Exact Dynamical Correlation Functions of Calogero-Sutherland Model and One-Dimensional Fractional Statistics
Z. N. C. Ha
One-dimensional model of non-relativistic particles with inverse-square interaction potential known as Calogero-Sutherland Model (CSM) is shown to possess fractional statistics. Us…
On Models with Inverse-Square Exchange
Z. N. C. Ha, F. D. M. Haldane
A one-dimensional quantum N-body system of either fermions or bosons with colors interacting via inverse-square exchange is presented in this article. A class of eigenstate…
