    Thermodynamics of trapped interacting bosons in one dimension (2001)
    College Park, Md. : American Institute of Physics (AIP)
    Journal of Mathematical Physics 42 (2001), S. 765-772

    Topics: Mathematics , Physics
    Notes: On the basis of Bethe ansatz solution of bosons with δ-function interaction in a one-dimensional potential well, the thermodynamics equilibrium of the system in finite temperature is studied by using the strategy of Yang and Yang. The thermodynamics quantities, such as specific heat, etc., are obtained for the cases of the strong coupling and weak coupling limits respectively. © 2001 American Institute of Physics.

    Notes: Abstract: On the basis of Bethe ansatz solution of the one dimensional SU(4) Hubbard-like model, we have studied its thermodynamic properties by means of the Yang-Yang thermodynamic Bethe ansatz. The Landé g factors for both spin and orbit are taken into account so as to describe electrons with orbital degeneracy. The free energy at low temperature is given and the specific heat both in the strong coupling and weak coupling limits are obtained. At the same time, we also point out the three possible critical fields, which may cause a quantum phase transition.
