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…
Quantum spin spiral ground state of the ferrimagnetic sawtooth chain
Roman Rausch, Matthias Peschke, Cassian Plorin +2
The ferrimagnetic phase of the sawtooth chain with mixed ferromagnetic nearest-neighbour interactions and antiferromagnetic next-nearest-neighbour interactions (within the…
Thermodynamics of the spin-half square-kagome lattice antiferromagnet
Johannes Richter, Oleg Derzhko, Jürgen Schnack
Over the last decade, the interest in the spin- Heisenberg antiferromagnet (HAF) on the square-kagome (also called shuriken) lattice has been growing as a model system of quan…
Anomalous thermodynamics of a quantum spin system with large residual entropy
J. Richter, J. Schulenburg, D. V. Dmitriev +2
In contrast to strongly frustrated classical systems, their quantum counterparts typically have a non-degenerate ground state. A counterexample is the celebrated Heisenberg sawtoot…
