Crossover temperature of the spin-1/2 XXZ chain with an impurity
Ryoko Yahagi, Jun Sato, Tetsuo Deguchi
We study exactly the effect of an impurity in the interacting quantum spin chain at low temperature by solving the integrable spin-1/2 XXZ periodic chain with an impurity through t…

Finite-temperature behavior of an impurity in the spin-1/2 XXZ chain
Ryoko Yahagi, Jun Sato, Tetsuo Deguchi
We study the zero- and the finite-temperature behavior of the integrable spin-1/2 XXZ periodic chain with an impurity by the algebraic and thermal Bethe ansatz methods. We evaluate…
