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…

Energy-momentum conservation laws in Finsler/Kawaguchi Lagrangian formulation
Takayoshi Ootsuka, Ryoko Yahagi, Muneyuki Ishida +1
We reformulate the standard Lagrangian formalism to a reparameterisation invariant Lagrangian formalism by means of Finsler and Kawaguchi geometry. In our formalism, various types…
