A solvable model of a one-dimensional quantum gas with pair interaction
H. -J. Schmidt, J. Bartke
We propose a solvable model of a one-dimensional harmonic oscillator quantum gas of two sorts of particles, fermions or bosons, which allows to describe the formation of pairs due…

Exact eigenstates and macroscopic magnetization jumps in strongly frustrated spin lattices
J. Richter, J. Schulenburg, A. Honecker +2
For a class of frustrated spin lattices including e.g. the 1D sawtooth chain, the 2D kagomé and checkerboard, as well as the 3D pyrochlore lattices we construct exact product eigen…

Quantum numbers for relative ground states of antiferromagnetic Heisenberg spin rings
K. Baerwinkel, P. Hage, H. -J. Schmidt +1
We suggest a general rule for the shift quantum numbers k of the relative ground states of antiferromagnetic Heisenberg spin rings. This rule generalizes well-known results of Mars…
