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…

Application of Kawaguchi Lagrangian formulation to string theory
Ryoko Yahagi, Akio Sugamoto
String-scalar duality proposed by Y. Hosotani and membrane-scalar duality by A. Sugamoto are reexamined in the context of Kawaguchi Lagrangian formulation. The characteristic featu…
