Resonant level model from a Krylov perspective: Lanczos coefficients in a quadratic model
Merlin Füllgraf, Jiaozi Wang, Jochen Gemmer +1
We study the Lanczos coefficients in a quadratic model given by an impurity interacting with a multi-mode field of fermions, also known as resonant level model. We analytically der…

Scaling of diffusion constants in the spin-1/2 XX ladder
R. Steinigeweg, F. Heidrich-Meisner, J. Gemmer +2
We study the dynamics of spin currents in the XX spin-1/2 ladder at finite temperature. Within the framework of linear response theory, we numerically calculate autocorrelation fun…
