Diffusion constants from the recursion method
Jiaozi Wang, Mats H. Lamann, Robin Steinigeweg +1
Understanding the transport behavior of quantum many-body systems constitutes an important physical endeavor, both experimentally and theoretically. While a reliable classification…
Emergence of unitary symmetry of microcanonically truncated operators in chaotic quantum systems
Jiaozi Wang, Jonas Richter, Mats H. Lamann +3
We study statistical properties of matrix elements of observables written in the energy eigenbasis and truncated to small microcanonical windows. We present numerical evidence indi…
Estimation of equilibration time scales from nested fraction approximations
Christian Bartsch, Anatoly Dymarsky, Mats H. Lamann +3
We consider an autocorrelation function of a quantum mechanical system through the lens of the so-called recursive method, by iteratively evaluating Lanczos coefficients, or solvin…
