Spin-Peierls instabilities of antiferromagnetic rings in a magnetic field
Valeria Lante, Ioannis Rousochatzakis, Karlo Penc +2
Motivated by the intriguing properties of magnetic molecular wheels at field induced level crossings, we investigate the spin-Peierls instability of antiferromagnetic rings in a fi…

The Role of the Exchange Interaction in the One-Dimensional -Component Hubbard Model
E. Szirmai, Ö. Legeza, J. Sólyom
The commensurate -filled -component Hubbard chain was investigated by bosonization and high-precision density-matrix renormalization-group analysis. It was found that depen…
