Infinite temperature spin dc conductivity of the spin-1/2 XXZ chain

Infinite temperature spin dc conductivity of the spin-1/2 XXZ chain

Using the Bethe ansatz method and the TBA equations for the higher spin integrable XXZ chain, the regular zero frequency contribution to the spin current correlation (spin dc conductivity) is analyzed for the spin-1/2 XXZ chain with an anisotropy \(0 \le \Delta
