摘要
The thermal and spin Drude weights of the spin-1/2 extended XY chain with three-spin interaction model [Euro. Phys Jour. B 32, 383 (2003)] are solved exactly. It is shown that the competition between the two-spin and three-spin interactions in the system influences the calculated quantities and leads to its characteristic features near the quantum critical point.
