Approximating thermodynamic equilibrium observables of quasi one-dimensional magnetic molecules and chains by thermal DMRG - a user perspective
L. Horstmann, J. Schnack
Density matrix renormalization group methods or tensor network methods in general can not only be used to determine ground states but also to evaluate thermal equilibrium propertie…

Finite-temperature Lanczos for anisotropic spin systems using triple-hybrid high-performance computing
J. Schnack
Lanczos concepts are often realized on supercomputers. In view of modern architectures of high-performance computing triple-hybrid schemes employing MPI, CPU-openMP as well as GPU-…

Magnetocaloric properties of centered molecular quantum spin systems
H. Meel, J. Schnack
We investigate the magnetocaloric properties of a class of centered magnetic molecules that are very similar in their magnetic properties. In particular, we study the magnetocalori…
