Decay of spin-spin correlations in disordered quantum and classical spin chains
Jonas Richter, Dennis Schubert, Robin Steinigeweg
The real-time dynamics of equal-site correlation functions is studied for one-dimensional spin models with quenched disorder. Focusing on infinite temperature, we present a compari…

Combining Dynamical Quantum Typicality and Numerical Linked Cluster Expansions
Jonas Richter, Robin Steinigeweg
We demonstrate that numerical linked cluster expansions (NLCE) yield a powerful approach to calculate time-dependent correlation functions for quantum many-body systems in one dime…

Magnetic properties of the Hubbard model on kagome stripes
O. Derzhko, M. Maksymenko, J. Richter +2
We consider the one-orbital -site repulsive Hubbard model on two kagome-like chains, both of which yield a completely dispersionless (flat) one-electron band. Using exact many-e…
