Hidden Dyson Universality in Inverse-Spectral Geometry
Momo Hayashi, Kazumitsu Sakai
Dyson universality typically manifests itself in local eigenvalue statistics. Here we show that its signature survives a nonlinear inverse-spectral reconstruction and reappears in…
Perfect transmission and parallel composition for quantum walks on graphs with two leads
Allan John Gerrard, Ryo Asaka, Kazumitsu Sakai
We study scattering for continuous-time quantum walks on finite graphs with two attached leads. We derive explicit formulae for the two-terminal scattering matrix in terms of chara…
Spin Drude weight for the integrable XXZ chain with arbitrary spin
Shinya Ae, Kazumitsu Sakai
Using generalized hydrodynamics (GHD), we exactly evaluate the finite-temperature spin Drude weight at zero magnetic field for the integrable XXZ chain with arbitrary spin and easy…
The thermal conductivity of the spin-1/2 XXZ chain at arbitrary temperature
Andreas Kluemper, Kazumitsu Sakai
Motivated by recent investigations of transport properties of strongly correlated 1d models and thermal conductivity measurements of quasi 1d magnetic systems we present results fo…
