We present an up-to-date survey of theoretical concepts and results in the field of one-
dimensional magnetism and of their relevance to experiments and real materials. Main …

An overview of one-and two-dimensional quantum spin systems based on transition-metal
oxides and halides of current interest is given, such as spin-Peierls, spin-dimer …

The first accounts of magnetism date back to the ancient Greeks who also gave magnetism
its name. It derives from Magnesia, a Greek town and province in Asia Minor, the …

In recent years, the study of ladder materials has developed into a well-established area of
research within the general context of strongly correlated electrons. This effort has been …

In this paper we continue and extend a systematic study of plateaux in magnetization curves
of antiferromagnetic Heisenberg spin-1/2 ladders. We first review a bosonic field-theoretical …

The magnetization process of the S= 1/2 Heisenberg chain with next-nearest-neighbor
(NNN) and alternating nearest-neighbor interactions is investigated using the bosonization …

We study a one-dimensional ladder of two coupled XXZ spin chains and identify several
distinct gapless symmetry-enriched critical phases. These have the same unbroken …

We investigate the effect of a magnetic field on a bosonic ladder. We show that such a
system leads to the one-dimensional equivalent of a vortex lattice in a superconductor. We …

We show that non-frustrated and frustrated ladders in a magnetic field can be systematically
mapped onto an XXZ Heisenberg model in a longitudinal magnetic field in the limit where …

We study the occurrence of plateaux and jumps in the magnetization curves of a class of
frustrated ladders for which the Hamiltonian can be written in terms of the total spin of a rung …
