Thermodynamics and spin-charge separation of one-dimensional strongly repulsive three-component fermions
The low-temperature thermodynamics of one-dimensional strongly repulsive SU(3) fermions in the presence of a magnetic field is investigated via the YangYang thermodynamic Bethe ansatz method. The analytical free energy and magnetic properties of the model at low temperatures in a weak magnetic field are derived via the WienerHopf method. It is shown that the low-energy physics can be described by spin-charge separated conformal field theories of an effective TomonagaLuttinger liquid and an...[Show more]
