Note on the thermodynamic Bethe Ansatz approach to the quantum phase diagram of the strong coupling ladder compounds
M. T. Batchelor, X. -W. Guan, A. Foerster +1
We investigate the low-temperature phase diagram of the exactly solved su(4) two-leg spin ladder as a function of the rung coupling and magnetic field by means of t…

Thermodynamic properties of an integrable quantum spin ladder with boundary impurities
M. T. Batchelor, X. -W. Guan, A. Foerster +2
An integrable quantum spin ladder based on the SU(4) symmetry algebra with boundary defects is studied in the framework of boundary integrability. Five nontrivial solutions of the…
