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 …

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 …

Abstract The Coupled Cluster Method (CCM) is one of the most powerful and universally
applied techniques of quantum many-body theory. In particular, it has been used extensively …

We establish the phase diagram of the strongly interacting Bose-Hubbard model defined on
a two-leg ladder geometry in the presence of a homogeneous flux. Our work is motivated by …

We study the quantum phases of bosons with repulsive contact interactions on a two-leg
ladder in the presence of a uniform Abelian gauge field. The model realizes many …

Motivated by recent work on the non-Hermitian skin effect in the bosonic Kitaev-Majorana
model, we study the quantum criticality of interacting bosonic Kitaev-Hubbard models on a …

We have succeeded in synthesizing single crystals of a new organic radical 3-Cl-4-FV [3-(3-
chloro-4-fluorophenyl)-1, 5-diphenylverdazyl]. Through the ab initio molecular orbital …

A large number of symmetry-protected topological (SPT) phases have been hypothesized
for strongly interacting spin-1/2 systems in one dimension. Realizing these SPT phases …

We investigate the ground-state phase diagram of the S= 1 2 two-leg XXZ spin-ladder
system with an isotropic interchain coupling. In this model, there is the Berezinskii-Kosterlitz …

Spin-ladders are quantum magnetic systems at the crossroads between one and two
dimensions that have attracted increasing interest during the last decades due to unique …
