Thermodynamics and Excitations of the Supersymmetric t− J Model
نویسنده
چکیده
The free energy of the supersymmetric t − J model is expressed in terms of finite temperature excitations above thermodynamic equilibrium. This reveals that the free energy has the form of noninteracting fermions with temperature dependant excitation spectra. We also discuss the ground state and zero temperature excitations.

Spin-Charge Separation at Finite Temperature in the Supersymmetric t-J Model with Long-Range Interactions
Thermodynamics is derived rigorously for the 1D supersymmetric t-J model and its SU(K, 1) generalization with inverse-square exchange. The system at low temperature is described in terms of spinons, antispinons, holons and antiholons obeying fractional statistics. They are all free and make the spin susceptibility independent of electron density, and the charge susceptibility independent of mag...
متن کاملSuper algebra and Harmonic Oscillator in Anti de Sitter space
The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space. Then we apply the supersymmetric Quantum Mechanics approach to solve our differential equation. In this paper we have solved Schrodinger equation for harmonic oscillator in AdS spacetime by supersymmetry approach. The shape...
متن کاملElementary excitations of one-dimensional t-J model with inverse-square exchange.
We identify exact excitation content of the intermediate states for the oneparticle Green’s functions, spin-spin and (charge) density-density correlation functions of the periodic one-dimensional t-J model with inverse square exchange. The excitations consist of neutral S = 1/2 spinons and spinless (charge −e) holons with semionic fractional statistics, and bosonic (charge +2e) “anti-holons” wh...
متن کاملSpectrum and Thermodynamics of the 1 D Supersymmetric t - J Model with 1 / r 2 Exchange and Hopping
We derive the spectrum and thermodynamics of the 1D supersymmetric t-J model with long range hopping and spin exchange using a set of maximal spin eigenstates. This spectrum confirms the recent conjecture that the asymptotic Bethe-ansatz spectrum is exact. By empirically determining the spinon degeneracies of each state, we are able to explicitly construct the free energy.
متن کاملSpin excitations in the integrable open quantum group invariant supersymmetric t – J model
The integrable quantum group splq(2, 1)-invariant supersymmetric t–J model with open boundaries is studied via an analytic treatment of the Bethe equations. An su(2) feature is seen to hold for states at or close to half-filling. For these states the eigenvalues of the transfer matrix of the t–J model satisfy a set of su(2) functional relations. The finite-size corrections to the relevant eigen...
