Fine structure of the nonlinear Drude weights in the spin-1/2 XXZ chain
Yuhi Tanikawa, Hosho Katsura
We study nonlinear Drude weights (NLDWs) for the spin-1/2 XXZ chain in the critical regime at zero temperature. The NLDWs are generalizations of the linear Drude weight. Via the no…

Exact results for nonlinear Drude weights in the spin-1/2 XXZ chain
Yuhi Tanikawa, Kazuaki Takasan, Hosho Katsura
Nonlinear Drude weight (NLDW) is a new concept which characterizes the nonlinear transport in quantum many-body systems. We investigate these weights for the spin-1/2 XXZ chain in…
