Journal ArticleDOI
Polyoxometalates: Fascinating structures, unique magnetic properties
Ulrich Kortz,Achim Müller,Joris van Slageren,Joris van Slageren,Jürgen Schnack,Naresh S. Dalal,Martin Dressel +6 more
TL;DR: In this article, several discrete molecular transition metal and lanthanide-containing polyoxo-tungstates and -molybdates with a focus on their magnetic properties are reported.
Journal ArticleDOI
Macroscopic magnetization jumps due to independent magnons in frustrated quantum spin lattices.
TL;DR: If the maximal number of local magnons scales with the number of spins in the system, which is the case for the Kagomé lattice, the effect persists in the thermodynamic limit and gives rise to a macroscopic jump in the zero-temperature magnetization curve just below the saturation field.
Journal ArticleDOI
Molecular dynamics for fermions
Hans Feldmeier,Jürgen Schnack +1 more
TL;DR: The time-dependent variational principle for many-body trial states is used to discuss the relation between the approaches of different molecular-dynamics models that describe indistinguishable fermions as mentioned in this paper.
Journal ArticleDOI
A unitary correlation operator method
Journal ArticleDOI
Classical and Quantum Magnetism in Giant Keplerate Magnetic Molecules
Achim Müller,Marshall Luban,Christian Schröder,Robert Modler,Paul Kögerler,Maria Axenovich,Jürgen Schnack,Paul C. Canfield,Sergey L. Bud'ko,Neil Harrison +9 more
TL;DR: Complementary theoretical modeling methods are presented for the classical and quantum Heisenberg model to explain the magnetic properties of nanometer-sized magnetic molecules, resulting in excellent quantitative agreement between experimental data and theoretical results.
